In order that those skilled in the art will better understand the present invention, a technical solution in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in which it is apparent that the described embodiments are only some embodiments of the present invention, not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the present invention without making any inventive effort, shall fall within the scope of the present invention.

It should be noted that the terms "first," "second," and the like in the description and the claims of the present invention and the above figures are used for distinguishing between similar objects and not necessarily for describing a particular sequential or chronological order. It is to be understood that the data so used may be interchanged where appropriate such that the embodiments of the invention described herein may be implemented in sequences other than those illustrated or otherwise described herein. Furthermore, the terms "comprises," "comprising," and "having," and any variations thereof, are intended to cover a non-exclusive inclusion, such that a process, method, system, article, or apparatus that comprises a list of steps or elements is not necessarily limited to those steps or elements expressly listed but may include other steps or elements not expressly listed or inherent to such process, method, article, or apparatus.

For convenience of description, the following will describe some terms or terminology involved in the embodiments of the present invention:

Packet transmission technology: packet transmission technology is a data transmission scheme that breaks data into a series of packets (or called packets) that are then transmitted over a network. Such transmission schemes are commonly used in network environments such as the internet and local area networks. In packet transmission technology, data is divided into packets of different sizes, each of which contains address information for transmission and reception, and a part of the data. The data packets can reach the destination through different paths in the transmission process, and are reassembled into the original data at the receiving end. Advantages of packet transmission techniques include flexibility, reliability, and efficiency. Since data packets can be transmitted through different paths, data can be successfully transmitted even if network congestion occurs or some paths are not available. In addition, packet transmission techniques can also improve network utilization because data packets can be transmitted in parallel.

Sliding window protocol: a data transmission protocol is characterized in that a window range is maintained by a transmitting end and a receiving end, and the window range is used for limiting the speed of transmitting data by the transmitting end and the speed of receiving data by the receiving end. The transmitting end and the receiving end are provided with a window with a fixed size, the window of the transmitting end represents a data range which can be transmitted, and the window of the receiving end represents a data range which can be received. When the transmitting end transmits data, the transmitting end can transmit the data outside the window only after the receiving end confirms that the data inside the window is received. When the receiving end receives the data, the receiving end can only send confirmation information to the sending end after receiving the data in the window, and the confirmation information indicates successful receiving. The sliding window protocol can effectively control the data transmission speed and avoid data loss and overload. Meanwhile, the data transmission efficiency can be improved, and the transmission delay can be reduced. In network communication, a sliding window protocol is widely used in data transmission protocols such as TCP.

As described in the background art, the transmission rate of bluetooth in the related art is low, and the requirements of large data volume and high rate cannot be satisfied. In view of the above drawbacks, the embodiments of the present invention provide a data transmission optimization method and apparatus.

According to an embodiment of the present invention, there is provided a method embodiment of a data transmission optimization method, it should be noted that the steps shown in the flowchart of the drawings may be performed in a computer system such as a set of computer executable instructions, and that although a logical order is shown in the flowchart, in some cases the steps shown or described may be performed in an order different from that shown or described herein.

Fig. 2 is a flowchart of a data transmission optimization method according to an embodiment of the present invention, as shown in fig. 2, the method includes the steps of:

Step S202, obtaining the quality index of the link, and adjusting the size of the data packet according to the quality index, wherein the link is a physical connection structure of the connection device in the network communication, and the data packet is a data unit transmitted in the network communication.

Optionally, the quality index includes, but is not limited to: the RSSI value, the packet loss rate, the error rate and the like can judge the index value of the current network state.

For example, it may be determined whether the current network condition is good by the following link quality index values: 1) Signal Strength (RSSI): signal strength is typically used to measure the power level of a wireless signal, a higher RSSI value typically means a stronger signal, which may mean that the network conditions are good; 2) Signal-to-noise ratio (SNR): signal-to-noise ratio is the ratio of signal strength to background noise strength, a higher SNR value generally indicates better signal quality, as the signal is easier to detect and resolve in noise; 3) Packet Loss Rate (Packet Loss Rate): the packet loss rate refers to the proportion of the lost data packets in the transmission process to the total transmission number, and the low packet loss rate generally means that the network is stable and the data transmission is more reliable; 4) Delay (Latency) or Round Trip Time (RTT): delay or RTT is the time required for a data packet to return from a sender to a receiver, and a low network delay generally means that the network reacts quickly and the user experience is better; 5) Throughput (Throughput): throughput is the amount of data that a network can successfully transmit per unit time, high throughput indicates that the network can transmit data at a higher speed, and generally indicates that the network condition is good; 6) Error Rate (Error Rate): bit Error Rate (BER) or Packet Error Rate (PER) measures the amount of data transmitted in error, a lower error rate generally means higher network quality; 7) Channel interference (CHANNEL INTERFERENCE): assessing possible interference on the network, including interference from other wireless devices, a lower interference level generally indicates better network conditions; 8) Network congestion: the network congestion degree can be evaluated by monitoring the network traffic and the utilization rate, and lower congestion means that the network resources are sufficient and the condition is good; 9) Connection stability: the stability of the network connection, including frequent disconnection and reconnection behavior, a stable connection means that the network conditions are good; 10 Quality of service (QoS) parameters: these parameters may include bandwidth guarantees, priority control, etc., which can guarantee the quality of network service.

According to the embodiment of the present invention, in the step S202, the adjusting the size of the data packet according to the quality index includes: comparing the quality index with an index threshold to obtain a comparison result; when the comparison result shows that the quality index is larger than the index threshold, increasing the size of the data packet until the size of the data packet reaches a first optimal threshold; and when the comparison result shows that the quality index is smaller than the index threshold, reducing the size of the data packet until the size of the data packet reaches a second optimal threshold, wherein the second optimal threshold is smaller than the first optimal threshold.

The above-described embodiments of the present invention will be described in detail with reference to fig. 3, and fig. 3 is a flowchart of an alternative data transmission optimization method according to an embodiment of the present invention. As shown in fig. 3, the size of the data packet is dynamically adjusted by using a packet transmission technology according to the current link quality index (such as RSSI value, packet loss rate, error rate, etc.), when the network condition is good and the error rate is low, the size of the data packet can be increased, so as to reduce the header overhead and acknowledgement times required for transmission and improve the data transmission efficiency; when the network condition is bad, such as weak signal or strong interference, reducing the size of the data packet can reduce the retransmission probability caused by channel error, thereby improving the success rate of transmission.

The size of the data packet is increased or decreased depending on the network condition and the data amount to be transmitted, in general, the size of the data packet can be increased appropriately under good network conditions, but stability of the network and real-time performance of data transmission are also required to be considered, and under weak signals or strong interference, the size of the data packet can be reduced appropriately to reduce retransmission probability caused by channel errors, experiments and tests can be performed according to network performance, the size of the data packet can be adjusted gradually, and the size most suitable for the current network conditions can be found.

Step S204, the data type of the data in the data packet is obtained, and the priority of the data packet is determined based on the data type, wherein the priority is used for determining the transmission sequence of the data packet.

As shown in the above figure 3, the data transmission scheduling can be self-adapted, priority data can be designed to classify profits, a priority scheduling algorithm is implemented to ensure that the advanced data can be transmitted preferentially, and the priority can be determined according to the different profits of the data by classifying the data so as to ensure that the data with high profits can be transmitted preferentially, thus the benefit of data transmission can be maximized, and the overall value of data transmission is improved.

According to the above embodiment of the present invention, in the above step S204, determining the priority of the data packet based on the data type includes: when the data type indicates that the transmission time efficiency of the data is not greater than the time efficiency threshold value, determining the priority of the data packet as high priority; when the data type indicates that the transmission requirement of the data is that the transmission is completed within a predetermined time period, the priority of the data packet is determined to be high.

The different priorities ensure that critical tasks and applications can obtain necessary network resources, while less important tasks are properly limited, and the priority of the current data is generally determined based on service requirements, user experience, network policies and technical requirements, and how to determine the priority of the data can be exemplified by the following aspects: 1) Real-time requirements: real-time services such as voice and video calls are often the highest priority because they require low latency and high reliability; 2) Key business application: data of key businesses such as financial transactions, telemedicine, emergency services and the like are generally given higher priority; 3) And (3) batch transmission: such as file download and backup tasks, can typically be subject to higher delays and therefore lower priority; 4) Quality of service (QoS) class: the network administrator can classify the data streams according to the service quality protocol to ensure that different data streams obtain proper network resources, and the QoS (quality of service) grades possibly comprise gold, silver and copper grades corresponding to high, medium and low priorities respectively; 5) Network protocol: some network protocols have built-in support for priority, e.g., the IEEE 802.1Q standard defines VLAN priority in ethernet frames, while the type of service (ToS) field of the IP header and subsequent DSCP (DIFFERENTIATED SERVICES Code Point) allow for priority classification of IP packets; 6) User protocols and policies: depending on the Service Level Agreements (SLAs) or corporate/network policies subscribed to by the user, the user or data flow may be assigned different priorities; 7) Interactive contents: such as web browsing and online gaming, generally require higher priority to ensure a good user experience; 8) Streaming media: such as video and audio streams, may have different priorities depending on the real-time requirements of the content; 9) Non-interactive content: such as email and software updates, may generally be assigned a lower priority; 10 Control message): network control and management messages are typically of higher priority; 11 User data): user data may be assigned different priorities depending on the importance and requirements of the application; 12 Application identification): the network equipment can identify different application programs through technologies such as Deep Packet Inspection (DPI) and the like, and allocate priorities according to the importance of the application programs; 13 User or device): data for a particular user (e.g., VIP client) or device (e.g., critical infrastructure) may be given higher priority; 14 Time sensitivity): for tasks that need to be completed within a specific time (e.g., real-time data analysis), the relevant data streams may be given high priority.

Step S206, the channel quality of the channel is obtained, and the channel with the channel quality larger than the first quality threshold is determined as the target channel, wherein the channel is a communication path for transmitting data on the link.

As shown in FIG. 3, the conditions of each channel, including interference and noise levels, can be monitored in real time, the most clear channel is selected for communication by using spectrum sensing technology, after the available surrounding channels are determined, the best channel (target channel) is dynamically selected based on channel quality (such as interference and signal to noise ratio), a CSMA/CA mechanism is implemented to avoid data packet collision, and a handshake mechanism is used to reduce hidden node problems.

The CSMA/CA mechanism is implemented herein to reduce collisions caused by simultaneous data transmission by multiple devices on the same channel, and is a network communication protocol for avoiding data collisions by listening to the channel, randomly backoff, and acknowledge, which is specifically as follows: 1) Listening to the channel: before sending data, the device first listens to whether the channel is idle or not, if the channel is busy (i.e. being used by other devices), the device will wait until the channel becomes idle; 2) Random back-off: even if the channel is idle, the device will not immediately transmit data and will wait for a random back-off time in order to reduce the possibility of collisions. This time is calculated based on a random number multiplied by a time unit (backoff coefficient); 3) Again listening to the channel: after the back-off time is over, the device listens to the channel again, and if the channel is still idle, the device will enter the next step; if the channel is busy, the device will re-perform random backoff; 4) Transmitting data: if the channel is idle, the device will send data; 5) Confirmation response: after transmitting the data, the transmitting device generally expects to receive an Acknowledgement (ACK) from the receiving device, and if the acknowledgement is received successfully, the transmitting device knows that the data has been successfully transmitted, and if the acknowledgement is not received, the transmitting device retries transmitting the data after another random back-off time has elapsed.

According to the above embodiment of the present invention, in the step S206, it is determined that the channel with the channel quality greater than the first quality threshold is the target channel, including at least one of the following: determining a channel with an interference value lower than an interference threshold as a target channel; determining a channel with a signal-to-noise ratio value higher than a signal-to-noise threshold value as a target channel; and determining a channel with the error rate lower than the error rate threshold as a target channel, wherein the error rate is the probability of error when data is transmitted through the channel.

For example, it can be judged whether or not the current channel is a good channel (target channel) from the following aspects (channel quality): 1) Low interference level: less external interference on the channel, such as interference from other wireless devices, natural sources (e.g., lightning) or artificial electromagnetic interference (e.g., motors and switching power supplies); 2) High signal-to-noise ratio (SNR): the signal strength (power) of the channel is high relative to the background noise level, which means that the signal is clearer and easily discernable by the receiver; 3) Low Bit Error Rate (BER): the error rate of the transmitted data in the channel is lower, which is typically associated with a high SNR, because stronger signals are more efficient at resisting noise and interference; 4) Stable transmission quality: the quality of the channel remains stable in time without frequent fluctuation, and the stability is helpful for maintaining continuous communication and avoiding frequent retransmission and connection interruption; 5) Suitable bandwidth: the channel can provide enough bandwidth to meet the requirement of data transmission, so that the information stream can be smoothly transmitted; 6) Unlicensed interference: no illegal or unauthorized signal interference exists on the channel, and local radio spectrum regulation and permission requirements are complied with; 7) Low delay: the propagation delay of the channel is low, which is particularly important for applications requiring real-time or near real-time response (e.g., voIP, online gaming, video conferencing, etc.); 8) Compatibility: the channel should be compatible with the frequency allocations of surrounding devices to avoid collisions with other services or devices.

According to the above embodiment of the present invention, after the step S206, that is, after determining that the channel with the channel quality greater than the first quality threshold is the target channel, the method further includes: acquiring the current channel quality of a target channel according to a preset period; and when the current channel quality is lower than a second quality threshold, switching the data transmitted by the target channel to other target channels with the current channel quality being higher than the first quality threshold for transmission, wherein the second quality threshold is smaller than the first quality threshold.

In the process of data transmission, the channel quality of each channel needs to be monitored in real time, so that when the channel quality is reduced to a certain threshold value, the channel can be quickly and seamlessly switched to a channel with better quality to continue data transmission.

Step S208, the transmission load and the transmission capacity of the target channel are obtained, and the transmission task of the target channel is allocated according to the transmission load and the transmission capacity, wherein the transmission load represents the data flow in the target channel.

As shown in fig. 3, multiple channels may be used to transmit data in parallel, and the allocation of data transmission may be adjusted in real time according to the load and performance of each channel, so as to optimize the overall transmission efficiency, which may be achieved by dynamically adjusting the weight of data distribution or switching channels, so as to maintain the load balance of each channel, and avoid overload or congestion of a single channel.

According to the above embodiment of the present invention, in the above step S208, allocating a transmission task of a target channel according to a transmission load and a transmission capability includes: determining a current data traffic of the target channel based on the transmission load; determining a total data traffic for the target channel based on the transmission capability; and calculating according to the current data flow and the total data flow to obtain the transmission task of the target channel.

For example, the transmission tasks of the channels may be dynamically adjusted from several aspects: 1) Link quality assessment: the link quality of each bluetooth connection is continuously monitored, including indicators of signal strength, error rate, delay, etc. Dynamically adjusting the data transmission amount on each link based on the evaluation results; 2) Bandwidth measurement: periodically measuring the actual available bandwidth of each connection, and adjusting data allocation according to the measurement result; 3) Data segmentation: dividing a large data stream into a plurality of smaller data packets and distributing the data packets according to the performance characteristics of each connection; 4) Scheduling algorithm: implementing a scheduling algorithm, such as Round-Robin (Round-Robin), weighted fair Queuing (WEIGHTED FAIR Queuing, WFQ), or shortest queue first (Shortest Queue First), to ensure that data is evenly distributed across the paths; 5) And (3) adaptability adjustment: dynamically adjusting the data allocation strategy according to the change of network conditions (such as signal strength change caused by the change of the position of the mobile device); 6) And (3) flow control: using a flow control mechanism to avoid congestion on any one connection, reducing the amount of data sent to that connection when congestion is detected; 7) Priority consideration: for data with different priorities, different transmission strategies can be adopted, so that the data with high priority is ensured to be transmitted quickly; 8) Error recovery mechanism: when an error occurs in one path, the data is quickly rerouted to the other path so as to avoid transmission delay; 9) Feedback mechanism: the device may provide feedback information to the sender, including current transmission efficiency and possible problems, so that the sender may adjust the transmission policy.

In step S210, data is transmitted based on the transmission task using the target channel according to the priority of the data packet.

When transmitting data, the data transmission is carried out according to the priority of the data and the transmission task of each channel, so that the utilization rate of the channels can be increased, the data throughput of the network can be increased, and the interference to other devices can be reduced by combining effective channel management and power control.

According to the above embodiment of the present invention, the data transmission optimization method further includes: acquiring the transmission state of data in a target channel; determining that the transmission state indicates that data transmitted in error in the transmission process is data to be retransmitted; and retransmitting the data to be retransmitted.

As shown in fig. 3, the collision and retransmission can be reduced by implementing selective retransmission using error control and recovery, retransmitting only erroneous packets (data packets) instead of the entire window, and controlling the transmission rate using a sliding window protocol.

For example, a packet may be judged to be erroneous from the following aspects: 1) Acknowledgement mechanism (Acknowledgment Mechanism): the sender waits for an acknowledgement signal (ACK) of the receiver after sending the data packet, and if the ACK is not received within a predetermined timeout period, the sender can assume that the data packet is lost and resend it; 2) Sequence number (Sequence Numbering): each packet is assigned a unique sequence number and the receiving side examines the sequence number of the packet to determine if there is a packet loss (e.g., if packets with sequence numbers 1 and 3 are received but no packet with sequence number 2 is received, it can be inferred that packet with sequence number 2 is lost); 3) Checksum (Checksum): the head or tail of the data packet contains a checksum value which is calculated based on the content of the data packet, the receiving party recalculates the checksum of the received data packet and compares the checksum with the checksum in the data packet, and if the two checksum values are not matched, the data packet is indicated to have errors in the transmission process; 4) Cyclic redundancy check (Cyclic Redundancy Check, CRC): CRC is a more complex form of checksum that uses polynomial coding to detect errors in data packets, CRC is generally able to detect errors in data packets, and error detection is more accurate than simple checksums; 5) Frame check Sequence (FRAME CHECK Sequence, FCS): similar to CRC, FCS is a mechanism that is commonly used by the data link layer to detect transmission errors; 6) Timeout retransmission (Timeout Retransmission): if the receiving side does not receive the specific data packet within the preset timeout time, the transmitting side retransmits the data packet; 7) Negative acknowledgement (Negative Acknowledgment, NAK): if the receiving side detects an erroneous data packet, it can send a NAK signal to the transmitting side informing the transmitting side to retransmit the data packet; 8) Automatic repeat request (Automatic Repeat reQuest, ARQ): ARQ is an error control method that combines mechanisms such as acknowledgement, timeout, retransmission, etc., to ensure that all packets are transmitted correctly.

The sliding window protocol may indirectly affect power usage by optimizing data transmission by managing data flows and responding to network conditions. The sliding window protocol may be employed to control the transmission rate from several aspects to reduce collisions and retransmissions: 1) And (3) flow control: the sliding window protocol controls the data transmission rate of a sender by dynamically adjusting the window size, and when the network quality is poor, the window size is reduced to reduce the number of data packets transmitted in the network at the same time, thereby reducing retransmission possibly caused by interference or signal attenuation and indirectly reducing the requirement of transmission power; 2) Congestion control: such as congestion control mechanisms in the TCP protocol, when network congestion is detected (e.g., by packet loss), the transmission rate of the data is reduced, which means that the transmission power is reduced indirectly in high congestion situations, because the frequency of transmitting data is reduced; 3) Quality of service (QoS) policy: in some networks, the transmit power may be adjusted according to the QoS requirements of the data flows, although this is typically done at a lower network layer, the sliding window protocol may support this by controlling the transmission rate to the high priority data flows; 4) Protocol for energy consumption perception: in some energy-aware network protocols, the behavior of the sliding window may take into account the energy efficiency of the device, e.g., in wireless sensor networks, the protocol may limit the transmission rate to extend the battery life of the device, which may also indirectly reduce the transmission power; 5) Adaptive transmission power control: although the sliding window protocol itself does not control the transmit power, it may be used in conjunction with an adaptive transmit power control mechanism, e.g., if a device frequently retransmits data packets due to errors, there may be a mechanism to increase the transmit power to improve the transmission quality, and the sliding window protocol may reduce the need for such increased power by reducing retransmissions.

According to the above embodiment of the present invention, the data transmission optimization method further includes: acquiring distance data between a sending device and a receiving device of data; adjusting the transmission power of the device according to the distance data and the channel quality, wherein the device comprises a transmitting device and a receiving device; data is transmitted based on the transmission power.

As shown in fig. 3, the transmission power is dynamically adjusted according to the distance between the device and the opposite terminal and the channel quality, so as to optimize the energy efficiency, i.e. reduce the transmission power as much as possible on the premise of ensuring the data transmission quality, thereby achieving the purpose of energy saving.

In this embodiment, the data transmission optimization method further includes: acquiring the activity of data transmission in a target channel; and when the activity level is determined to be lower than the activity level threshold value, controlling the equipment to enter a low-power mode, wherein the low-power mode refers to the equipment entering a standby or sleep state.

When the data transmission is not active, the device can enter a low power consumption mode and wake up quickly according to the data transmission requirement. The data transmission of the current channel may be judged to be in an inactive state from several aspects: 1) And (3) no data packet transmission: the network device does not detect any inbound or outbound packets for a predetermined period of time; 2) Quiet period: the communication protocol may define a quiet period during which the connection is deemed inactive if there is no data exchange; 3) Timeout: many web services and applications have timeout settings, and if there is no data transfer within the timeout period, the session or connection may be closed; 4) Below a certain threshold: some systems may define the active state based on the frequency or amount of data transmission. If the data transmission rate is below a certain threshold, it may be considered inactive; 5) The user does not interact: for client applications, if no user has done any action for a period of time resulting in no data transfer, this may also be considered inactive; 6) The application program is run in the background: when an application is running in the background and is not in network communication, it may be considered inactive on data transmission; 7) Wait state: the device or application may be in a state waiting to receive data, but if no data arrives for a long time, this waiting state may transition to an inactive state.

When data transmission is inactive, the device may be put into a low power mode by: 1) Reducing processor speed: many devices may reduce the clock frequency of the CPU or turn off some cores to reduce power consumption; 2) Turning off or reducing the peripheral power supply: screens, hard disks, wireless adapters, and other peripherals may be turned off or put into a low power mode; 3) Reducing network activity: the network interface may reduce its operating frequency, reduce the frequency of checking network packets, or turn off the radio transmitter entirely; 4) Memory state change: the device may transfer data from a fast but energy-consuming RAM to a slow but energy-saving storage, or use a low-power-consumption RAM state; 5) System response delay: devices that enter a low power state may have significant delays in waking up because time is required to resume a normal operating state; 6) Indicator light or status change: some devices may indicate that they have entered a low power mode by means of an indicator light or by displaying status information on a user interface.

According to the above, the quality index of the link can be obtained first, and the size of the data packet can be adjusted according to the quality index, wherein the link is a physical connection structure of the connection device in the network communication, and the data packet is a data unit transmitted in the network communication; acquiring the data type of data in the data packet, and determining the priority of the data packet based on the data type, wherein the priority is used for determining the transmission sequence of the data packet; acquiring the channel quality of a channel, and determining the channel with the channel quality larger than a first quality threshold as a target channel, wherein the channel is a communication path for transmitting data on a link; acquiring transmission load and transmission capacity of a target channel, and distributing transmission tasks of the target channel according to the transmission load and the transmission capacity, wherein the transmission load represents data flow in the target channel; the data is transmitted by utilizing the target channel based on the transmission task according to the priority of the data packet, the size of the data packet is dynamically adjusted according to the link quality index in network communication, the transmission task is dynamically allocated according to the transmission load and the transmission capacity of the channel, the channel with higher channel quality is selected to transmit the data according to the priority of the data packet based on the transmission task, the technical effect of transmitting more data in a given time is realized, the channel utilization rate is improved, the data throughput of the network is increased, and the data transmission efficiency is improved.
