Embodiment Construction

[0051] The routing method for UAV network communication includes the following steps:

[0052] Step 1. Randomly deploy UAV network nodes;

[0053] Step 2. Link information and node information are exchanged between UAV network nodes for link awareness and neighbor discovery;

[0054] Step 3. UAV network nodes elect cluster-head nodes according to link information and node information, and UAV network nodes that are not selected as cluster-head nodes are non-cluster-head nodes;

[0055] Step 4. The non-cluster-head node sends a join request to the cluster-head node, and the cluster-head node establishes the topology structure information in the cluster after receiving the join request;

[0056] Step 5. Each cluster-head node notifies the non-cluster-head nodes in the cluster of the topology information in the cluster established by itself, so that the non-cluster-head nodes in the cluster can establish the topology structure in the cluster; each cluster-head node sends informa...

Abstract

The invention relates to a routing method for unmanned aerial vehicle network communication. The method comprises the following steps: 1, randomly deploying unmanned aerial vehicle network nodes; 2, interacting link information and node information between the nodes to perform link perception and neighbor discovery; 3, electing a cluster head node according to the link information and the node information; 4, the non-cluster head node sending a join request to the cluster head node, and the cluster head node establishing topological structure information in the cluster after receiving the joinrequest; 5, each cluster head node informing the non-cluster head nodes in the cluster of the topological structure information in the cluster, so that the non-cluster head nodes in the cluster establish a topological structure in the cluster; each cluster head node sending information indicating that the cluster head node is a cluster head to other cluster head nodes, and establishing a clusterhead network topology structure between the cluster head nodes; and 6, establishing a routing table according to the link information, the node information and the in-cluster topological structure. The method is good in expandability, high in network stability and real-time performance, low in energy consumption and particularly suitable for large-scale unmanned aerial vehicle network communication.

Description

[0001] (1) Technical field: [0002] The invention relates to a routing method for network communication, in particular to a routing method for network communication of an unmanned aerial vehicle. [0003] (two), background technology: [0004] UAV has the characteristics of low cost, high mobility, good concealment and strong adaptability, and is widely used in military and civilian fields. The current UAV application is basically a stand-alone mission, which has relatively large limitations, low survivability and is not conducive to expansion. It will face many restrictions when performing missions. Information processing capabilities and transmission delays put forward higher requirements, so the application of UAVs is gradually developing from a single machine to multi-machine cooperation to complete complex tasks. In order to realize multi-machine coordination of UAVs, it is necessary to realize stable communication between multiple machines. [0005] For the network com...
