Take the application as a certain game as an example. In order to ensure the smoothness of the game, it is necessary to ensure that the terminal device has a good network status to ensure that the background running data of the game can be quickly uploaded or downloaded between the local and remote servers of the terminal device. In order to ensure that the game’s cached data can be stored in a timely manner, it is necessary to ensure that the terminal device has sufficient storage space to ensure that the game's running data can be completely stored; further, in order to ensure the rapid processing of game tasks, it is necessary to ensure that the terminal device has a powerful Computing processing power to ensure the processing of game tasks.

Using this method, it does not consider the remaining energy and communication capabilities of the cloud virtual machine. When the task volume of the terminal device is large, the remaining energy and communication capability of the cloud virtual machine cannot satisfy the terminal device. The amount of tasks required is possible.

In contrast, with the multi-terminal task allocation method disclosed in the embodiments of the present application, after the requester terminal issues a task request, at least one executor terminal capable of executing the task in the task request is selected from multiple cooperative terminals. On the one hand, When selecting the executor terminal, the performance parameters of the executor terminal are taken as consideration factors, thereby eliminating the possibility that the executor terminal in the above-mentioned prior art solution cannot meet the task volume demand of the terminal device.

As an existing technology for implementing computing offloading, another solution is disclosed: terminal devices use computing offloading technology to completely offload part or all of the tasks to a single Multi-access Edge Computing (MEC) server on the base station side. A single MEC server and terminal device cooperate to complete the tasks on the terminal device, and the task processing efficiency is low. In addition, this method fails to utilize the capabilities of other terminals around the terminal device. If the distance between the MEC service and the terminal device is relatively long, this method may cause a longer transmission delay.

In contrast, through the multi-terminal task distribution method disclosed in the embodiments of the present application, the tasks of the requester terminal can be distributed to different executor terminals that can communicate with the requester terminal for collaborative processing, which solves the aforementioned problems of the prior art. The problem of long transmission delay in the scheme,

Through the multi-terminal task distribution method disclosed in the embodiments of the present application, compared with the above-mentioned prior art, the task of the requester terminal is distributed to multiple different executor terminals for processing, and the focus of processing by multiple different terminals is It is also different according to its own performance, and the task processing efficiency and reliability are high.

Combining the scenario shown in Figure 1 and the flowchart shown in Figure 4 (a), Figure 4 (b), Figure 4 (c), Figure 4 (d), and Figure 4 (e), the The multi-terminal allocation method of the specific implementation of the application will be further introduced.

Example 1

The terminals that access the cellular network include mobile phone 1, mobile phone 2 to mobile phone N, mobile phone 1 as the requester terminal, mobile phone 2 to mobile phone N as cooperative terminals, the natural number N represents the serial number of the cooperative terminal, and the number of alternative cooperative terminals is ( N-1). In the case that a cooperative terminal is needed to assist the mobile phone 1 in implementing the solution of the present application, the number of cooperative terminals must be non-zero, so N must be greater than 2.

Communication is established between mobile phone 1 and the control center, mobile phone 2 to mobile phone N, and the control center, and communication can be established between mobile phone 2 and mobile phone N as a collaboration terminal. The service executed in mobile phone 1 is a game service. For example, if the game service requires mobile phone 1 to download background data from a remote server, the data download rate needs to reach 1MBps. After mobile phone 1 downloads the background data, mobile phone 1 needs to calculate the background data (e.g. Game screen rendering, etc.), the computing capacity reaches 500MIPS, and the background data is downloaded and the calculation results obtained by calculating the background data need to be stored to avoid repeated downloads and calculations. If the data to be stored is 200M, the storage space is required to be at least 200M. Because the battery of mobile phone 1 is too low, computing performance, communication performance and storage performance cannot meet the above business requirements of the game business, mobile phone 1 is completely unable to handle the above business requirements of the game business based on its current performance, and the above business requirements (calculation Task, communication task and storage task) are allocated to mobile phone 2 to mobile phone N.

Please refer to FIG. 4(a). FIG. 4(a) is a schematic flowchart of a multi-terminal task allocation method disclosed in an embodiment of the application.

The detailed steps of the multi-terminal task allocation method are described below based on Figure 4(a):

Step S40: The mobile phone 1 serves as the requester terminal to send service requirements to the control center, where the service requirements include but are not limited to computing tasks (computing capacity at least 500MIPS), communication tasks (data download rate at least 1MBps), and storage tasks (storage space) At least 200M).

Step S41: Mobile phone 2 to mobile phone N report their respective performance parameters to the control center. The performance parameters of mobile phone 2 to mobile phone N include but are not limited to the main frequency of the processor, the external frequency of the processor, the frequency of the front side bus of the processor, etc. , The processor’s main frequency, the processor’s external frequency, the processor’s front-side bus frequency, the processor’s occupancy rate and other performance parameters can all determine the processor’s processor speed. The processor speed can also be called the performance parameters of the mobile phone. The storage space of the memory (including the total storage capacity of the memory and the remaining space of the memory), the signal strength of the mobile phone's access to the network (communication capability), the remaining power of the mobile phone, and the communication link between the mobile phone 2 to the mobile phone N and the control center Channel gain, etc. can all be used as the performance parameters of the mobile phone 2 to the mobile phone N, and the control center stores the received performance parameters of the mobile phone 2 to the mobile phone N to the control center first.

It should be noted that when mobile phone 2 to mobile phone N report their respective performance parameters to the control center, they can report periodically or in accordance with the report instruction issued by the control center (the control center will report to the The mobile phone 2 to the mobile phone N issue a report instruction), so that the control center can obtain the performance parameters of the mobile phone 2 to the mobile phone N in real time.

Step S42: The control center determines the time difference from the acquisition time of the performance parameters reported by the mobile phone 2 to the mobile phone N to the current time. For mobile phones with the time difference greater than the information age threshold (first threshold), the control center sends the time difference greater than the information age threshold The (first threshold) mobile phone sends a capability report command to notify mobile phones whose time difference is greater than the information age threshold (first threshold) to re-report their performance parameters; for mobile phones whose time difference is not greater than the information age threshold (first threshold), the control center will As a candidate for performing tasks in the business requirements of the mobile phone 1, the information age threshold can be set according to experience values. The embodiment of this application does not limit the size of the information age threshold. Illustratively, the information age threshold is set in the embodiment of this application. The age threshold is set to 1 second. Therefore, the time difference between the acquisition time of the performance parameters reported by the mobile phone 2 and the mobile phone N to the current time is only when it does not exceed the information age threshold, it will be regarded as a candidate for the performer terminal, ensuring the performance parameters of the mobile phone 2 to the mobile phone N The real-time performance of the mobile phone further allocates an appropriate amount of tasks to the mobile phone 2 to the mobile phone N, so that the current performance of the mobile phone 2 to the mobile phone N can satisfy the execution of the tasks in the mobile phone 1, and the reliability is high.

Please refer to FIG. 4(b). FIG. 4(b) is a schematic diagram of specific implementation of step S42 in FIG. 4(a) disclosed in an embodiment of the application.

Step S420: The control center calculates the time difference between the reporting time of the performance parameters of the mobile phone 2 to the mobile phone N and the current time.

Step S421: The control center separately judges whether the time difference between mobile phone 2 and mobile phone N is greater than the information age threshold. For mobile phones whose time difference is greater than the information age threshold, proceed to step S422; for mobile phones whose time difference is not greater than (less than or equal to) the information age threshold, proceed to Step S423.

Step S422: The control center sends a capability report instruction to notify the mobile phones whose time difference is greater than the information age threshold to re-report their performance parameters, and then proceeds to step S43.

The time difference between the acquisition time of the performance parameters reported from mobile phone 2 to mobile phone N to the current time is only when it does not exceed (less than or equal to) the information age threshold, it will be regarded as a candidate for the executor terminal, ensuring that mobile phone 2 to mobile phone N The real-time performance of the performance parameters can further allocate an appropriate amount of tasks to the mobile phone 2 to the mobile phone N, so that the current performance of the mobile phone 2 to the mobile phone N can meet the execution of the tasks in the mobile phone 1, and the reliability is high.

Step S423: The control center takes the mobile phone whose time difference is not greater than the information age threshold as a candidate for executing the task in the service requirement of the mobile phone 1, and then proceeds to step S43.

Step S43: The control center selects at least one capable of executing as the executor from candidate mobile phones that meet the time difference between the acquisition time of the performance parameters reported by mobile phone 2 and mobile phone N to the current moment (assuming that mobile phone 2 to mobile phone N are all candidate phones) Terminal, and distribute communication tasks, computing tasks, and storage tasks to each executor’s terminal.

The following describes the selection of cooperative terminals for different tasks.

Among them, for the communication tasks in the business requirements of mobile phone 1, the control center is based on the data transmission rate uploaded from mobile phone 2 to mobile phone N, the channel gain of the communication link between mobile phone 2 to mobile phone N and the control center and the remaining power from the mobile phone 2 Select an executor terminal with the ability to perform communication tasks from the mobile phone N. When the control center selects the performer terminal based on the data transmission rate, the channel gain of the communication link between the mobile phone 2 to the mobile phone N and the control center, and the remaining power, the data transmission rate, channel gain, and remaining power are weighted to obtain the mobile phone 2 to the weighted value of the communication performance of each mobile phone in the mobile phone N, and then sort the weighted values of each communication performance in the order from high to low, and select the mobile phones as the execution according to the task amount of the communication task in the order of the weighted value from high to low.者terminal.

The weighted value of communication performance can be calculated by the following formula:

Communication performance weighted value = a ₁ *communication capability +b ₁ *remaining power +c ₁ *channel gain

The values of a ₁ , b ₁ and c ₁ can be set according to empirical values. In principle, _{the value of a 1} is greater than b ₁ and c ₁ .

After the control center calculates the communication performance weighted value of each mobile phone, it is assumed that the communication performance weighted values Com_2 and Com_4 of mobile phone 2 and mobile phone 4 are in the first and second place respectively, and the data transmission rate of mobile phone 2 and mobile phone 4 are both less than 1MBps (mobile phone The data transfer rate of 2 is 0.6MBps, the data transfer rate of mobile phone 4 is 0.7MBps), the data download rate required by the communication task is at least 1MBps, only mobile phone 2 or mobile phone 4 cannot complete the communication task, mobile phone 2 and mobile phone 4 data The sum of the transmission rate is 1.3MBps, which is greater than 1MBps. Therefore, the communication task can be completed by mobile phone 2 and mobile phone 4. Mobile phone 2 and mobile phone 4 are from the remote server at a data download rate of 0.6MBps and a data download rate of 0.7MBps, respectively Download the background data. In this way, the coordinated data download rate of the mobile phone 2 and the mobile phone 4 meets the requirement that the data download rate required by the communication task is at least 1 MBps.

It is worth noting that when mobile phone 2 and mobile phone 4 download background data, the data stream of the background data to be downloaded for the game service in mobile phone 1 is transmitted from mobile phone 1 to the control center, and the control center downloads the data based on mobile phone 2 and mobile phone 4 The rate is to allocate downloads to mobile phone 2 and mobile phone 4, for example, allocate the amount of background data to be downloaded to mobile phone 2 and mobile phone 4 according to a ratio of 2:3.

For the computing tasks in the business requirements of the mobile phone 1, the control center selects an executor terminal capable of performing computing tasks from the mobile phone 2 to the mobile phone N based on the processor speed, channel gain, and remaining power uploaded from the mobile phone 2 to the mobile phone N. When the control center selects an executor terminal capable of performing computing tasks from mobile phone 2 to mobile phone N based on the processor speed, channel gain, and remaining power uploaded from mobile phone 2 to mobile phone N, the processor speed, channel gain, and remaining power Perform weighting to obtain the calculation performance weighted value of each mobile phone from mobile phone 2 to mobile phone N, and then sort each calculation performance weight value in order from high to low, and according to the task amount of the calculation task according to the calculation performance weight from high to low Select the mobile phone as the executor terminal in sequence.

Among them, the calculation performance weighted value can be calculated by the following formula:

Calculation performance weighted value = a ₂ * processor speed + b ₂ * remaining power + c ₂ * channel gain

The values of a ₂ , b ₂ and c ₂ can be set according to empirical values. In principle, _{the value of a 2} is greater than b ₂ and c ₂ .

After the control center calculates the calculation performance weighted value of each mobile phone, suppose that the calculation performance weighted value Co_2 and Co_5 of mobile phone 2 and mobile phone 5 are ranked first and second, and the computing power of mobile phone 2 and mobile phone 5 are both less than 500MIPS (mobile phone 2 The processor speed of mobile phone 5 is 200MBps, and the processor speed of mobile phone 5 is 300MBps), and the computing power required for the calculation task is at least 500MIPS. The calculation task cannot be completed by mobile phone 2 or mobile phone 5. The sum of the processor speeds of mobile phone 2 and mobile phone 4. It is 500MIPS, therefore, the calculation task can be completed by mobile phone 2 and mobile phone 5. Mobile phone 2 and mobile phone 5 calculate the background data downloaded from the remote server at a processing speed of 200MBps and 300MBps respectively. Thus, mobile phone 2 and mobile phone 5 The synergistic processing speed of the two meets the requirements of computing tasks.

It is worth noting that after mobile phone 2 and mobile phone 4 download the background data allocated by the control center from the remote server at a data download rate of 0.6MBps and a data download rate of 0.7MBps, respectively, if both mobile phone 2 and mobile phone 4 can If it can communicate with other mobile phones as the executor terminal, the background data downloaded by the mobile phone 2 from the remote server is transmitted to the processor of the mobile phone 2, and the processor of the mobile phone 2 performs calculation and processing, and the mobile phone 4 downloads the background data from the remote server. The data is transmitted to the mobile phone 5 that performs calculation tasks, and the processor of the mobile phone 5 performs calculation processing. If neither mobile phone 2 nor mobile phone 4 can communicate with other mobile phones as the executor terminal, the background data downloaded by mobile phone 4 from the remote server is first sent to the control center, and then forwarded to mobile phone 5 by the control center. The processor processes the background data forwarded by the control center.

Among them, for the storage tasks in the business requirements of mobile phone 1, the control center selects from mobile phone 2 to mobile phone N based on the storage space of the memory uploaded from mobile phone 2 to mobile phone N (the remaining storage space of the memory), channel gain and remaining power Performer terminal with the ability to perform storage tasks. The control center weights the storage space, channel gain, and remaining power when selecting an actor terminal capable of performing storage tasks from mobile phone 2 to mobile phone N based on the storage space, channel gain, and remaining power uploaded from mobile phone 2 to mobile phone N. Obtain the storage performance weighted value of each mobile phone in mobile phone 2 to mobile phone N, and then sort the storage performance weighted values from high to low, and according to the task volume of storage tasks, the storage performance weighted values are in order from high to low. Select the mobile phone as the executor terminal.

Among them, the storage performance weighted value can be calculated using the following formula:

Storage performance weighted value = a ₃ * storage space + b ₃ * remaining power + c ₃ * channel gain

The values of a ₃ , b ₃ and c ₃ can be set according to empirical values. In principle, _{the value of a 3} is greater than b ₃ and c ₃ .

After the control center calculates the storage performance weighted value of each mobile phone, it is assumed that the storage performance weighted value Ca_6 of mobile phone 6 is ranked first, the storage space of mobile phone 6 is greater than 200M, and the storage capacity required by the storage task is 200M (including mobile phone 2 and The data downloaded from the background by mobile phone 4 and the calculation results of mobile phone 2 and mobile phone 5), therefore, the storage task can be completed by mobile phone 6. It is worth noting that if mobile phone 2, mobile phone 4, and mobile phone 5 can communicate directly with mobile phone 6, Then, the mobile phone 2 and the mobile phone 4 transmit the background data downloaded from the remote server to the mobile phone 6, and the mobile phone 2 and the mobile phone 5 also transmit the calculation result to the mobile phone 6, and the memory of the mobile phone 6 is stored. If mobile phone 2, mobile phone 4, and mobile phone 5 cannot directly communicate with mobile phone 6, the background data downloaded from the remote server by mobile phone 2 and mobile phone 4 will be transmitted to the control center, and mobile phone 2 and mobile phone 5 will also forward the calculation results to In the control center, the data of the mobile phone 2, the mobile phone 4, and the mobile phone 5 are forwarded to the mobile phone 6 by the control center, and stored in the memory of the mobile phone 6.

If the mobile phone 2, the mobile phone 5, and the mobile phone 6 as the executor terminal can directly communicate with the mobile phone 1 as the requester terminal, the mobile phone 2 as the executor terminal will store the calculation result, the mobile phone 5 the calculation result, and the mobile phone 6 The data (background data and calculation results) cached in the executor are sent directly to the mobile phone 1. If the mobile phone 2, the mobile phone 5, and the mobile phone 6 as the executor terminal cannot communicate with the mobile phone 1 as the requester terminal, the mobile phone 1 as the executor terminal The mobile phone 2 sends the calculation result, the mobile phone 5 calculates the result, and the mobile phone 6 first sends the data buffered in the memory to the control center, and then the control center forwards it to the mobile phone 1.

The types of performance parameters uploaded by each mobile phone described in the above embodiments are specifically shown in Figure 4(c). The performance parameters uploaded in Figure 4(c) include: communication capability (data download rate), computing capability (processor Speed), cache capacity (storage space), remaining power, channel gain, and upload time.

The unit of communication capacity (data download rate) is MBps, the unit of computing capacity (processor speed) is MIPS, the unit of cache capacity is G, the unit of remaining power is mah, and the unit of channel gain is |h|∧2, upload The time is displayed in hours/minutes/seconds.

The values of the performance parameters uploaded by each mobile phone described in the above embodiments are specifically shown in Figure 4(d). The communication capacity, computing capacity, cache capacity, remaining power and channel gain of the mobile phone 2 are Com_2, Co_2, Ca_2, and p_2, respectively. And c_2, the communication capacity, computing capacity, cache capacity, remaining power and channel gain of mobile phone 4 are Com_4, Co_4, Ca_4, p_4, and c_4 respectively, and the communication capacity, computing power, cache capacity, remaining power and channel gain of mobile phone 5 are respectively Com_5, Co_5, Ca_5, p_5, and c_5. The communication capability, computing capability, cache capability, remaining power, and channel gain of the mobile phone 5 are Com_6, Co_6, Ca_6, p_6, and c_6, respectively.

The following takes business requirements as an example to describe the specific implementation of step S43 in Fig. 4(a), please refer to Fig. 4(e), Fig. 4(e) is the step in Fig. 4(a) disclosed in the embodiment of this application Schematic diagram of the specific implementation of S43.

Step S430: The control center judges whether multiple mobile phones are needed to complete the communication task according to the task volume of the communication task and the performance parameters of the candidate mobile phones. If so, the multiple candidate mobile phones (mobile phone 2 and mobile phone 4) are used as executor terminals, and step S431 , If not, go directly to step S432.

For communication tasks, the control center selects multiple candidate mobile phones for collaborative processing, which improves the processing efficiency of communication tasks.

Step S431: The control center reasonably allocates the communication tasks to the mobile phone 2 and the mobile phone 4 and enters step S432.

It is worth noting that when mobile phone 2 and mobile phone 4 download background data, the data stream of the background data to be downloaded for the game service in mobile phone 1 is transmitted from mobile phone 1 to the control center, and the control center downloads the data based on mobile phone 2 and mobile phone 4 The rate is to allocate downloads to mobile phone 2 and mobile phone 4 respectively. For example, according to the ratio of 2:3, mobile phone 2 and mobile phone 4 are allocated the amount of background data to be downloaded to achieve a reasonable allocation of communication tasks to mobile phone 2 and mobile phone 4.

Step S432: The control center judges whether the mobile phone 2 and the mobile phone 4 can directly communicate with the mobile phone 5 performing the calculation task and the mobile phone 6 performing the storage task.

Step S433: If the mobile phone 2 and the mobile phone 4 can directly communicate with the mobile phone 5 performing the computing task and the mobile phone 6 performing the storage task, the background data downloaded by the mobile phone 2 from the remote server is transferred to the processor of the mobile phone 2. The processor of the mobile phone performs calculation processing, and the mobile phone 2 sends the background data and calculation results to the mobile phone 6 for storage; the mobile phone 4 transmits the background data downloaded from the remote server to the mobile phone 5 that performs the calculation task, and the mobile phone 5’s processor Perform calculation processing, and the mobile phone 5 sends the processing result to the mobile phone 6 for storage.

In this way, when the mobile phone 2 and the mobile phone 4 can directly communicate with the mobile phone 5 performing computing tasks and the mobile phone 6 performing storage tasks, data sharing can be directly realized, and the data usage efficiency is high.

Step S434: The mobile phone 2 and the mobile phone 4 cannot directly communicate with the mobile phone 5 performing the calculation task and the mobile phone 6 performing the storage task. The mobile phone 4 uploads the downloaded background data to the control center, and the control center forwards the background data to the mobile phone. 5. After the mobile phone 5 receives the background data, it processes it, uploads the processing result to the control center, and the control center forwards the processing result to the mobile phone 6 for storage.

Step S435: If the mobile phone 1 and the mobile phone 6 performing the storage task can communicate directly, the mobile phone 1 directly obtains the data stored in the mobile phone 2, the mobile phone 4 and the mobile phone 5 from the mobile phone 6, if the mobile phone 1 and the mobile phone 6 performing the storage task cannot For direct communication, the control center forwards the data in the mobile phone 6 to the mobile phone 1. The control center judges whether the mobile phone 1 has acquired all the execution results executed by the mobile phone 2, the mobile phone 4 and the mobile phone 5, if yes, executes step S44, if not, returns to step S432.

Step S44: The mobile phone 1 merges the acquired execution results of each executor terminal.

In the multi-task distribution method disclosed in Embodiment 1 of the present application, after a requester terminal sends a task request, at least one executor terminal capable of performing the task in the task request is selected from a plurality of cooperative terminals. On the one hand, when selecting In the case of an executor terminal, the performance parameters of the executor terminal are taken into consideration, thereby eliminating the possibility that the executor terminal in the prior art cannot meet the task volume requirements of the terminal device, and the executor terminal is selected according to the performance parameters of each mobile phone , It can handle business more efficiently. In addition, the remaining power of the mobile phone as a collaboration terminal is considered to avoid accidental shutdown caused by low power of the mobile phone, with high reliability. On the other hand, the tasks of the requester terminal can be distributed to different executor terminals that can communicate with the requester terminal for collaborative processing, which solves the problem of shorter transmission delay in the second method in the prior art. In addition, compared with In the prior art, the tasks of the requester terminal are distributed to different executor terminals for processing, and the task processing efficiency and reliability are high.

In the following, in conjunction with the scenario shown in FIG. 2 and the flowchart shown in FIG. 5, another embodiment of the multi-terminal allocation method according to the specific implementation manner of the present application will be further introduced.

Example 2

The terminals connected to the cellular network include mobile phone 1, mobile phone 2 to mobile phone N, where N is a natural number greater than 2, mobile phone 1 as the requester terminal, mobile phone 2 to mobile phone N as the cooperation terminal, mobile phone 1 as the requester terminal, and mobile phone 1 as the cooperation terminal Proximity communication is possible between mobile phone 2 and mobile phone N. The service executed in mobile phone 1 is a game service. For example, if the game service requires mobile phone 1 to download background data from a remote server, the data download rate needs to reach 1MBps. After mobile phone 1 downloads the background data, mobile phone 1 needs to calculate the background data (e.g. Game screen rendering, etc.), the computing capacity reaches 500MIPS, and the background data is downloaded and the calculation results obtained by calculating the background data need to be stored to avoid repeated downloads and calculations. If the data to be stored is 200M, the storage space is required to be at least 200M. Because the battery of mobile phone 1 is too low, computing performance, communication performance and storage performance cannot meet the above business requirements of the game business, mobile phone 1 is completely unable to handle the above business requirements of the game business based on its current performance, and the above business requirements (calculation Task, communication task and storage task) are allocated to mobile phone 2 to mobile phone N.

Please refer to FIG. 5, which is a schematic flowchart of another multi-terminal task allocation method disclosed in an embodiment of the application.

The detailed steps of the multi-terminal task allocation method are described below based on FIG. 5:

Step S50: The mobile phone 1 as the requester broadcasts the service requirements and the performance parameters of the mobile phone 1 itself to the mobile phone 2 to the mobile phone N in the domain. The download rate is at least 1MBps) and storage tasks (the storage space is at least 200M). In this embodiment of the application, the business requirements include computing tasks, communication tasks, and storage tasks as examples.

Step S51: After the mobile phone 2 to the mobile phone N as the executor terminal receive the service requirements broadcast by the mobile phone 1, they form corresponding task clusters for the communication tasks, computing tasks and storage tasks in the service requirements. The task clusters include but are not limited to communication clusters. , Computing cluster and storage cluster, each task cluster includes at least one mobile phone.

Step S52: In the above task clusters, a cluster head will be selected as the control center in the cluster, specifically: the mobile phones in each task cluster broadcast their own performance parameters, that is, each mobile phone belonging to the communication cluster broadcasts itself The performance parameters belong to each mobile phone in the computing cluster to broadcast its own performance parameters, and to each mobile phone in the storage cluster to broadcast its own performance parameters.

Among them, for the mobile phones in the communication cluster, its performance parameters include but are not limited to data transmission rate, connectivity and remaining power. Connectivity refers to the degree of connectivity of a mobile phone (specifically, all mobile phones are considered Point, when the proximity communication between the two mobile phones is established, when the channel gain between the two mobile phones is greater than the threshold, it is considered that there is connectivity between the two mobile phones, and there is an edge connection between the two mobile phones. Connectivity refers to the number of edges connected to the mobile phone. The greater the connectivity of a mobile phone, the better the connectivity of the mobile phone).

When selecting the cluster head in the communication cluster, the data transmission rate, connectivity and remaining power of each mobile phone in the communication cluster are weighted to obtain the communication performance weighted value of each mobile phone in the communication cluster, and each communication performance weighted value is increased from high Sort to low, and select the mobile phone with the highest communication performance weight as the cluster head of the communication cluster (in the embodiment of this application, mobile phone 2 is used as the cluster head of the communication cluster). The communication performance weight can be calculated by the following formula:

Communication performance weighted value = a ₄ *communication capacity + b ₄ * remaining power + c ₄ * connectivity

The values of a ₄ , b ₄ and c ₄ can be set according to empirical values. In principle, _{the value of a 4} is greater than b ₄ and c ₄ .

For mobile phones in the computing cluster, its performance parameters include, but are not limited to, processor speed, connectivity, and remaining power.

When selecting the cluster head in the calculation cluster, the processor speed, connectivity and remaining power of each mobile phone in the calculation cluster are weighted to obtain the communication performance weighted value of each mobile phone in the calculation cluster, and each calculation performance weighted value is increased from high Sort to the lowest, and select the mobile phone with the highest computing performance weight as the cluster head of the computing cluster (in the embodiment of this application, mobile phone 3 is used as the cluster head of the computing cluster), and the computing performance weight can be calculated by the following formula:

Calculation performance weighted value = a ₅ * processor speed + b ₅ * remaining power + c ₅ * connectivity

The values of a ₅ , b ₅ and c ₅ can be set according to empirical values. In principle, _{the value of a 5} is greater than b ₅ and c ₅ .

For the mobile phones in the storage cluster, its performance parameters include but are not limited to storage space, connectivity, and remaining power.

When selecting the cluster head in the storage cluster, the storage space, connectivity, and remaining power of each mobile phone in the storage cluster are weighted to obtain the storage performance weighted value of each mobile phone in the storage cluster, and each storage performance weighted value is increased from high to Sort by low, and select the mobile phone with the highest storage performance weight value as the cluster head of the storage cluster (in the embodiment of this application, mobile phone 4 is used as the cluster head of the storage cluster). The storage performance weight value can be calculated by the following formula:

Storage performance weighted value = a ₆ * storage space + b ₆ * remaining power + c ₆ * connectivity

The values of a ₆ , b ₆ and c ₆ can be set according to empirical values. In principle, _{the value of a 6} is greater than b ₆ and c ₆ .

Step S53: The mobile phone serving as the cluster head in each task cluster judges whether it can complete the tasks in the cluster according to its own performance parameters. If it can, go to step S54, if not, go to step S55.

Among them, as described above, the computing capacity of the computing task in the mobile phone 1 is at least 500MIPS, the data download rate of the communication task is at least 1MBps, and the storage space of the storage task is at least 200M.

For the mobile phone 2 of the cluster head of the communication cluster, the task in the cluster is to download background data from the remote server, and its data download rate is used as the basis for judging whether the task in the cluster can be completed, and it is used as the cluster head of the communication cluster. The mobile phone judges whether it can complete the tasks in the cluster according to its own performance parameters. The mobile phone as the cluster head of the communication cluster judges whether its data download rate can meet the download rate of 1MBps. If the data download rate of the cluster head of the communication cluster is not If it is less than 1MBps, the cluster head can handle the communication task alone.

For the mobile phone 3 that calculates the cluster head of the cluster, the task in the cluster is to perform calculations on the remote server downloading background data, and its processor speed is used as the basis for judging whether the tasks in the cluster can be completed. According to its own performance parameters, the mobile phone of the head can judge whether it can complete the tasks in the cluster, including: the mobile phone as the cluster head of the computing cluster judges whether the processor speed can meet the processing speed of 500MIPS, if the processor speed of the cluster head of the computing cluster is not less than 500MIPS, the cluster head of the computing cluster can handle the communication task separately.

For the mobile phone 4 that caches the cluster head of the cluster, the task in the cluster is to cache the remote server downloading background data and the calculation result of the mobile phone 3, and the storage space of the mobile phone 4 is used as the judgment of whether the task in the cluster can be completed According to the basis, the mobile phone as the cluster head of the computing cluster can judge whether it can complete the tasks in the cluster according to its own performance parameters. The mobile phone as the cluster head of the cache cluster judges whether the storage space can meet the storage requirement of 200M, if the cluster head of the cache cluster If the storage space is not less than 200M, the cluster head of the cache cluster can handle the communication task separately.

Step S54: The cluster head in each task cluster completes the tasks in the cluster and proceeds to step S56.

Step S55: The cluster heads respectively select the remaining performer terminals in their respective clusters to jointly process tasks in the cluster and proceed to step S56. Among them, when the cluster heads of each task cluster select the remaining execution terminals in their respective clusters, they are sorted from high to low according to the communication performance weighted value, calculation performance weighted value and storage performance weighted value in each cluster. , The cluster head selects the remaining performer terminals according to the performance weighted value in descending order, until the performance of the cluster head of the task cluster and the performance of the remaining performer terminals are superimposed to meet the task requirements.

Among them, for the cluster head of the communication cluster, it is assumed that the weighted value of the communication performance of mobile phone 2 as the cluster head ranks first, the data transmission rate of mobile phone 2 is less than 1MBps (the data transmission rate of mobile phone 2 is 0.6MBps), and mobile phone 4 is used as communication The cluster members in the cluster rank second in the weighted value of communication performance. The data transmission rate of mobile phone 4 is 0.8MBps, and the data download rate required by the communication task is at least 1 MBps. Only mobile phone 2 as the cluster head cannot complete the communication task. The sum of the data transfer rates of 2 and 4 is 1.4MBps, which is greater than 1MBps. Therefore, the communication task can be completed by both mobile 2 and mobile 4. Mobile 2 and mobile 4 have a data download rate of 0.6 MBps and 0.8 MBps of data, respectively The download rate downloads the background data from the remote server. In this way, the coordinated data download rate of the mobile phone 2 and the mobile phone 4 meets the requirement that the data download rate required by the communication task is at least 1 MBps.

It is worth noting that when mobile phone 2 and mobile phone 5 download background data, the data stream of the background data to be downloaded for the game service in mobile phone 1 is transmitted from mobile phone 1 to mobile phone 2, which is the cluster head, and mobile phone 2 downloads it according to its own data. The speed sum and the data download rate of mobile phone 5 allocate downloads to mobile phone 2 and mobile phone 5 respectively. For example, according to the ratio of 4:5, mobile phone 2 and mobile phone 5 are allocated the amount of background data to be downloaded respectively.

Among them, for the cluster heads in the computing cluster, if the computing performance weighted value of the mobile phone 5 as the cluster head ranks first in the cluster, the processor speed of the mobile phone 5 is less than the 500MBps required by the computing task (the processor of the mobile phone 5 The speed is 300MBps), mobile phone 2 is a cluster member in the computing cluster, and its computing performance weighted value ranks second in the computing cluster. The processor speed of mobile phone 2 is 200MBps. Obviously, mobile phone 5 as the cluster head cannot be completed independently For computing tasks, the sum of the processor speeds of mobile phone 2 and mobile phone 5 is 500MBps, which meets the requirements of the computing task. Therefore, the computing task can be completed by mobile phone 2 and mobile phone 5. Mobile phone 2 and mobile phone 5 process background data at a processor speed of 300MBps and a processing speed of 200MBps, respectively. In this way, the same data download rate of both mobile phone 2 and mobile phone 5 is satisfied. The processor speed required for computing tasks is 500MBps.

Among them, for the cluster heads in the storage cluster, if the storage performance weighted value of the mobile phone 6 as the cluster head in the storage cluster ranks first, the storage space of the mobile phone 6 is greater than 200M, and the storage capacity required by the storage task is 200M ( Including the data downloaded from the background by the mobile phone 2 and the mobile phone 4 and the calculation results of the mobile phone 2 and the mobile phone 5), therefore, the storage task can be completed by the mobile phone 6.

Step S56: The cluster heads in each task cluster judge whether the executor terminals in the cluster can directly communicate with the executor terminals in the clusters of other task clusters, if yes, go to step S57, and if not, go to S58.

Step S57: Performer terminals in each task cluster share data with each other.

For example, after mobile phone 2 and mobile phone 4 download the background data allocated by mobile phone 2 as the cluster head at a data download rate of 0.6 MBps and a data download rate of 0.8 MBps, respectively, if mobile phone 2 and mobile phone 4 in the communication cluster can Proximity communication with mobile phone 5 in the computing cluster (specifically whether the channel gain between mobile phone 2 or mobile phone 4 and mobile phone 5 is greater than the threshold value to determine, if the channel gain between mobile phone 2 or mobile phone 4 and mobile phone 5 is greater than the threshold value, then it is indicated The mobile phone 2 and the mobile phone 4 can communicate with the mobile phone 5 in the computing cluster), the background data downloaded by the mobile phone 2 from the remote server is transmitted to the processor of the mobile phone 2, and the processor of the mobile phone 2 performs calculation and processing. The background data downloaded by the end server is transmitted to the mobile phone 5, and the processor of the mobile phone 5 performs calculation processing.

If both the mobile phone 2 as the cluster head of the communication cluster and the mobile phone 5 as the cluster head of the computing cluster can communicate with the mobile phone 6 nearby, and the mobile phone 4 as a cluster member of the communication cluster cannot communicate with the mobile phone 6 nearby, the mobile phone 4 will The background data downloaded by the remote server is transmitted to the mobile phone 2, and the mobile phone 2 transmits the background data downloaded by itself and the background data downloaded by the mobile phone 4 to the mobile phone 6, and the cluster head mobile phone 2 of the communication cluster and the cluster head mobile phone 5 of the computing cluster will calculate the results It is also transmitted to the mobile phone 6, and stored in the memory of the mobile phone 6. The mobile phone 2 as the cluster head of the communication cluster, the cluster member mobile phone 4 of the communication cluster, and the mobile phone 5 as the cluster head of the computing cluster can all communicate with the mobile phone 6, then The data generated by the mobile phone 2, the mobile phone 4 and the mobile phone 5 are all transmitted to the mobile phone 6.

Step S58: The cluster heads in each task cluster forward the data of the executor terminals in the respective clusters.

If neither mobile phone 2 nor mobile phone 4 can communicate with other mobile phones as executor terminals, the background data downloaded by mobile phone 4 from the remote server is first sent to cluster head mobile phone 2, which is a communication cluster, and then mobile phone 2 will transfer the data from the mobile phone. The background data of 4 is forwarded to the mobile phone 5, and the processor of the mobile phone 5 processes the background data forwarded by the mobile phone 2.

Step S59: The mobile phone 1 judges whether it has acquired all the execution results of the performer's terminals in each task cluster. If so, it proceeds to step S60, and if not, it returns to step S56.

It is worth noting that if the cluster head mobile phone 2, the cluster member mobile phone 4, the cluster head mobile phone 5, and the cluster head mobile phone 6 as the executor terminal can directly communicate with the mobile phone 1 as the requester terminal, then the executor terminal The mobile phone 2 sends the calculation result and background data, the background data downloaded by the mobile phone 4, the mobile phone 5 calculates the result, and the mobile phone 6 sends the data (background data and calculation result) cached in the memory directly to the mobile phone 1, if it is used as a cluster of the executor terminal The member mobile phone 4 cannot communicate with the mobile phone 1 as the requester terminal, and the mobile phone 2 as the head of the communication cluster forwards the data of the mobile phone 4 to the mobile phone 1.

Step S60: The mobile phone 1 merges the acquired execution results of each executor terminal.
