Description

Technical Field

[0001] The present invention relates to the technical field of wireless ad hoc networks, and in particular to a configuration updating method for wireless ad hoc networks. Background Art

[0002] A wireless ad hoc network (WAN) is a special wireless communication network consisting of multiple wireless nodes (such as mobile devices, sensors, etc.). These nodes can achieve communication and data transmission through mutual cooperation and routing selection without a central control node.

[0003] Wireless ad hoc networks are widely used in fields such as the Internet of Things, emergency communications, and military communications. These fields have high demands for rapid deployment and flexible configuration. To meet these demands, wireless ad hoc networks need to adopt an effective network-wide configuration synchronization update strategy to ensure that all nodes can coordinate and update configurations in a consistent manner, thereby maintaining communication stability and reliability.

[0004] Currently, the most common methods for synchronously updating the full-network configuration of wireless ad hoc networks mainly use broadcast and multicast. The implementation of broadcast and multicast relies on network data protocols. This requires that data packets (broadcast packets and multicast packets) not only carry configuration update information but also network data protocol metadata (such as protocol headers). This additional metadata increases the length of the data packet to a certain extent, occupying more network bandwidth. Especially in large-scale networks, it will cause relatively large network overhead, affecting the normal transmission of other data, and reducing the data transmission efficiency and performance of the wireless ad hoc network.

[0005] Therefore, the present invention proposes a configuration update method for a wireless ad hoc network to solve the above technical problems. Summary of the Invention

[0006] The present invention proposes a configuration update method for a wireless ad hoc network. By using a dedicated control channel to transmit configuration information data, unnecessary metadata network overhead in the wireless ad hoc network configuration update process is reduced, and the efficiency and performance of configuration information data transmission are improved. By setting an update flag field in the configuration information data, each node can synchronously update its own configuration, ensuring the consistency of the wireless ad hoc network configuration update.

[0018] S22. The master node periodically sends the first configuration information data to the slave node through a dedicated control channel.

[0019] Furthermore, the step S3 specifically includes the following steps:

[0022] S33, the slave node periodically sends the second configuration information data to each node through the special control channel.

[0023] Further, the step S4 specifically comprises the following steps:

[0024] S41, the master node receives the second configuration information data sent by the slave node through the special control channel;

[0025] S42, the master node compares the second configuration information data with the first configuration information data, when the value of the second configuration parameter is the same as the value of the first configuration parameter for the first time, the master node adds 1 to the value of the first update node count;

[0026] S43, when the value of the first update node count is the same as the value of the number N of the slave nodes, the master node confirms that all the slave nodes have updated the second configuration parameter;

[0027] S44, the master node sets the value of the first update flag to a;

[0028] S45, the master node periodically sends the first configuration information data to the slave node through the special control channel.

[0029] Further, the step S5 specifically comprises the following steps:

[0030] S51, the slave node receives the first configuration information data sent by the master node through the special control channel;

[0038] (1) the value of the first update node count is 0;

[0039] (2) the value of the first update node count is less than the value of the number of slave nodes N and the value of the first update node count is still not 0 within t seconds;

In this way, all nodes in the wireless ad hoc network can synchronously update their own configurations, ensuring the consistency of the wireless ad hoc network configuration update.

S43: When the value of the first update node count is the same as the value of the number of slave nodes N, the master node confirms that all the slave nodes have updated the second configuration parameters; S44. The master node sets the value of the first update flag to a; S45. The master node periodically sends the first configuration information data to the slave node through the dedicated control channel.

7. A configuration update method for a wireless ad hoc network according to claim 6, characterized in that: The step S5 specifically includes the following steps: S51, the slave node receives first configuration information data sent by the master node through the dedicated control channel; S52: When the slave node detects that the value of the first whether-to-update flag is a, the slave node sets the value of the second whether-to-update flag to a; S53, the slave node periodically sends the second configuration information data to each node through the dedicated control channel; S54. The slave node updates its own configuration according to the second configuration parameters.

8. The configuration update method of a wireless ad hoc network according to claim 7, characterized in that: The step S6 specifically includes the following steps: S61. The master node receives the second configuration information data sent by the slave node through the dedicated control channel; S62: The master node compares the second configuration information data with the first configuration information data. When the value of the second update flag is a for the first time and the value of the second configuration parameter is the same as the value of the first configuration parameter, the master node decrements the value of the first update node count by 1. S63. When the following two conditions are met: (1) The value of the first update node count is 0; (2) The value of the first update node count is less than the value of the number of slave nodes N and the value of the first update node count does not become 0 within t seconds; When one of the conditions is met, the master node confirms that all the slave nodes on the network have updated the value of the second update flag; S64. The master node updates its own configuration according to the first configuration parameters; S65. The master node changes itself into a slave node.

9. The configuration update method of a wireless ad hoc network according to claim 8, characterized in that: The dedicated control channel transmits data through a dedicated control protocol, and the content of the dedicated control protocol includes a node ID bit, a master-slave node flag bit, an update flag bit, an update node count bit, a configuration parameter bit, and a reserved bit.
