All other embodiments, which can be made by those skilled in the art based on the embodiments of the application without making any inventive effort, are intended to be within the scope of the application.
The wireless mesh network (Wireless Mesh Networks, also called wireless mesh network, etc.) is a novel network structure based on multi-hop routing and peer-to-peer network technologies, and is increasingly widely used as a communication technology of wireless interconnection. Most of the existing mesh network protocols are based on a fixed networking environment, and the mesh network can comprise dozens of node devices. The mesh network is connected with the Internet through a connection router, the node connected with the router is called a root node, the node connected with the root node is called a child node, and the child nodes are connected with each other besides the root node.
The embodiment of the application provides a data transmission method which is applied to a sending device, wherein the sending device is any node device in a mesh network. The transmitting device refers to a device that is to transmit data, for example, device a is to transmit data to device B, that is, device a is to communicate with device B, that is, device a is a transmitting device, and device B is a receiving device.
In the embodiment of the present application, as shown in fig. 1, the data transmission method mainly includes:
step 101, a channel identifier used for communication is obtained.
When the transmitting device communicates with the receiving device, the transmitting device and the receiving device operate on the same channel. Channel identification refers to a parameter that can uniquely determine the channel used by a device. In the WiFi6 standard, a BSS Color coloring mechanism is used, the channel identifiers are Color identifiers, the communication message carries the Color identifiers, the Color identifiers are the same, the equipment works in the same channel, channel interference exists, the Color identifiers are different, the equipment works in different channels, the channel interference does not exist, and normal communication can be achieved. The application is described with the channel identifier as the color identifier, but the channel identifier is not limited to be the color identifier only.
Step 102, determining that an interference device exists, wherein the interference device is node equipment in the mesh network, the interference device uses a channel corresponding to the channel identifier during communication, and the interference device does not comprise a sending device and a receiving device.
The interfering device refers to a device whose channel identifier is the same as that of the transmitting device, except for the transmitting device and the receiving device, and whose communication parameters satisfy preset conditions. The communication parameters include at least one of time delay and error rate, and other parameters can be included according to requirements. The communication parameters are used to represent the communication quality of the device. The communication parameters meet the preset conditions, and the time delay can be larger than the preset time delay, the bit error rate can be larger than the preset bit error rate, the time delay can be larger than the preset time delay, and the bit error rate is larger than the preset bit error rate. The communication parameters satisfy a preset condition indicating that the interfering device is communicating and is being interfered. For example: the device A is a transmitting device, the device B is a receiving device, the channel identifier of the device A is red, the devices with the channel identifier of red are the device A, the device B, the device C and the device D, and the error rate of the communication between the device C and the device D is larger than the preset error rate, so that the interference devices are the device C and the device D.
In a specific embodiment, the correspondence between the interference device and the channel identifier is obtained by at least one node device in the mesh network.
The node devices in the mesh network can communicate with each other, and at least one node device in the mesh network can acquire data sent by each node device in the mesh network. At least one node device in the mesh network can monitor a communication message of each node device in the mesh network, wherein the communication message carries a color identifier and a device identifier, and the device identifier refers to a parameter capable of uniquely determining the device, and for example, the device identifier can be a MAC address (Media Access Control Address, local area network address).
At least one node device in the mesh network extracts color identification and device identification from the communication message of each node device in the mesh network. And establishing an interference information comparison table according to the color identifier and the equipment identifier. And the interference information comparison table is stored with the corresponding relation between the color mark and the equipment mark, and the interference information comparison table is stored in a classified mode according to the color mark. For example: the color of the device A is identified as red, the color of the device B is identified as red, the color of the device C is identified as red, the color of the device D is identified as blue, the color of the device E is identified as blue, the color of the device F is identified as blue, the color of the device G is identified as blue, the interference information comparison table is stored in a classified manner according to the color identification, and the interference information comparison table is stored as follows: color is identified as red, and the corresponding device is identified as the MAC address of device A, the MAC address of device B and the MAC address of device C; color is identified as blue, and the corresponding device is identified as the MAC address of device D, the MAC address of device E, the MAC address of device F, and the MAC address of device G.
The channel used by each device is unchanged, i.e. the channel identifier of each device is fixed, and the transmitting device can judge whether the interference device corresponding to the channel identifier exists or not only by receiving the interference information comparison table transmitted by at least one node device in the mesh network and querying the interference information comparison table. At least one node device in the mesh network may also include a sending device, or the sending device may query the interference information comparison table stored in the sending device itself.
Step 103, controlling the initial transmission power to adjust to the target transmission power, and transmitting data to the receiving device according to the target transmission power.
The initial transmission power is controlled to be adjusted to the target transmission power, the initial transmission power is controlled to be increased to the target transmission power, the initial transmission power is controlled to be reduced to the target transmission power, the initial transmission power is controlled to be unchanged, and the interference equipment is instructed to be increased from the initial transmission power to the target transmission power. For example: the device A is a transmitting device, the device B is a receiving device, the interfering device is a device C and a device D, the initial transmission power of the device A and the device B can be controlled to be increased to a target transmission power, the transmission power of the device C and the transmission power of the device D are unchanged, the transmission power of the device A and the transmission power of the device B are also controlled to be unchanged, the initial transmission power of the device C and the device D is increased to the target transmission power, the mutual interference between the communication between the device A and the device B and the communication between the device C and the device D is avoided as much as possible, and the stability of data transmission is improved.
When interference equipment which uses the same channel with the sending equipment exists, the stability of data transmission is improved by adjusting the transmission power of the sending equipment, and the problem of abnormal communication among the equipment caused by the fact that a plurality of equipment use the same channel is solved.
In one embodiment, as shown in fig. 2, before controlling the initial transmission power to be adjusted to the target transmission power, the data transmission method further includes:
step 201, a communication distance between the receiving device and the obtaining device is obtained.
In one embodiment, obtaining a communication distance between the receiving device comprises: sending a heartbeat packet to a receiving device; receiving confirmation data returned by the receiving equipment according to the heartbeat packet; acquiring the sending time of sending the heartbeat packet and the receiving time of receiving the confirmation data; and acquiring the communication distance according to the sending time and the receiving time.
The confirmation data is confirmation information which is sent to the sending device after the receiving device confirms that the heartbeat packet sent by the sending device is received. According to the sending time and the receiving time, the communication distance is acquired, specifically: and acquiring the communication distance according to the difference between the receiving time and the transmitting time.
The communication distance does not need to be re-acquired every time, and can be any device corresponding to the color identifier when no communication exists between the devices corresponding to the same color identifier, sending a heartbeat packet to other devices corresponding to the color identifier according to an interference information comparison table in a time-sharing manner, acquiring acknowledgement data returned by the other devices corresponding to the color identifier according to the heartbeat packet, acquiring the sending time of sending the heartbeat packet, receiving the receiving time of the acknowledgement data, and acquiring the communication distance between the devices corresponding to the color identifier according to the difference between the receiving time and the sending time. If non-heartbeat communication among devices occurs in the heartbeat polling process, which means that devices in a channel corresponding to the channel identifier are in communication, the heartbeat detection is stopped, and communication abnormality is avoided. The communication distance and a standard value can be divided to obtain a proportionality coefficient, which is called a device heartbeat coefficient, and the device heartbeat coefficient is also stored in the interference information comparison table. When the communication distance needs to be acquired, the corresponding equipment heartbeat coefficient in the interference information comparison table is directly inquired. The device heartbeat coefficients of the devices may also be sorted in the interference information comparison table in order from small to large, or from large to small.
Because each node device in the mesh network has mobility and the position may change, the device heartbeat coefficient in the interference information comparison table needs to be dynamically adjusted, which may be that a heartbeat packet is sent periodically to determine the device heartbeat coefficient, or when a certain device moves, the moving device sends the heartbeat packet to the device using the same channel to update the device heartbeat coefficient.
Step 202, obtaining the data volume to be transmitted.
In step 203, the target transmission power is obtained according to the communication distance and/or the data amount.
In one embodiment, there is a positive correlation between the target transmission power and the communication distance, and/or there is a positive correlation between the target transmission power and the amount of data.
Positive correlation refers to the increase in the independent variable, which is followed by the increase in the dependent variable. There is a positive correlation between the target transmission power and the communication distance, i.e., the longer the communication distance, the greater the target transmission power. There is a positive correlation between the target transmission power and the amount of data, i.e. the larger the amount of data to be transmitted, the larger the target transmission power. The positive correlation exists between the target transmission power and the communication distance, and the positive correlation exists between the target transmission power and the data volume, which means that the longer the communication distance is, the larger the data volume to be transmitted is, and the larger the target transmission power is.
And under the condition that the communication distance is long, or the data volume to be transmitted is large, or the communication distance is long and the data volume to be transmitted is large, controlling the initial transmission power to be adjusted to the target transmission power can improve the stability of data transmission.
In a specific embodiment, there is a correspondence between the amount of data to be sent and the transmission time length, and the correspondence between the amount of data to be sent and the transmission time length is stored in a reference comparison table, where the reference comparison table is obtained through a large number of experimental tests, and dynamic adjustment is not needed. The target transmission power may be obtained according to the communication distance and/or the data amount by searching the corresponding transmission time length in the reference lookup table according to the data amount to be sent, and the target transmission power may be obtained according to the communication distance and/or the transmission time length.
In one embodiment, before controlling the initial transmission power to be adjusted to the target transmission power, the data transmission method further includes: it is determined that the interfering device is transmitting data packets using a channel corresponding to the channel identification.
Under the condition that the interference equipment is determined to transmit the data packet by using the channel corresponding to the channel identifier, the initial transmission power is required to be controlled to be increased to the target transmission power, and if the heartbeat packets are only transmitted regularly between the interference equipment to maintain the connection of the communication link, the initial transmission power is not required to be controlled to be increased to the target transmission power, so that the transmission power can be saved, and the transmission energy consumption can be reduced.
Further, after controlling the initial transmission power to be adjusted to the target transmission power, the data transmission method further includes: and if the data packet of the interference equipment is detected to be transmitted, adjusting the target transmission power to the initial transmission power. After the initial transmission power is controlled to be increased to the target transmission power, the data packet of the interference device is transmitted, and the target transmission power is reduced to the initial transmission power, so that the transmission power can be saved, and the transmission energy consumption can be reduced.
In a specific embodiment, determining that the interfering device is transmitting the data packet using the channel corresponding to the channel identifier includes: acquiring a target data volume transmitted by an interference device by using a channel corresponding to the channel identifier; comparing the target data volume with a preset data volume threshold; if the target data volume is larger than the preset data volume threshold value, determining that the interference equipment is transmitting the data packet by using the channel corresponding to the channel identifier.
The preset data amount threshold may be a preset value that is greater than the data amount of heartbeat packets that maintain the connection of the communication link. If the target data volume is larger than the preset data volume threshold, the interference devices are not used for transmitting heartbeat packets to maintain the connection of the communication link, but are used for communicating, and data packets with large data volumes are transmitted.
Or, a heartbeat packet for maintaining connection of the communication link may include a specific field, while a data packet transmitted by communication does not include the specific field, and if it is detected that data transmitted by the interfering device using a channel corresponding to the channel identifier does not include the specific field, it is determined that the interfering device is transmitting the data packet using the channel corresponding to the channel identifier.
In one embodiment, as shown in fig. 3, the data transmission method mainly includes:
step 301, at least one node device in the mesh network monitors a communication message of each node device in the mesh network, wherein the communication message carries a color identifier and an MAC address, and an interference information comparison table is established according to the color identifier and the MAC address.
Step 302, the transmitting device sends the heartbeat packet to the receiving device, receives the acknowledgement data returned by the heartbeat packet by the receiving device, obtains the sending time of sending the heartbeat packet and the receiving time of receiving the acknowledgement data, obtains the communication distance according to the sending time and the receiving time, divides the communication distance by a standard value to obtain a proportionality coefficient, namely a device heartbeat coefficient, and stores the device heartbeat coefficient in the interference information comparison table.
Step 303, dynamically adjusting the information of the interference information comparison table.
Step 304, the transmitting device searches the transmission time according to the corresponding relation between the data volume to be transmitted and the transmission time, and determines the transmission power optimization coefficient according to the transmission time and the communication distance.
In step 305, a target transmission power is calculated based on the initial transmission power and the transmission power optimization coefficient.
In step 306, the transmitting device transmits data to the receiving device according to the target transmission power.
