Embodiment Construction

[0057] In order to make the technical problems, technical solutions and advantages to be solved by the present invention clearer, the following will describe in detail with reference to the drawings and specific embodiments.

[0058] The present invention aims at the existing problem that there is no effective clustering method for the cluster UAV ad hoc network, and provides a clustering UAV ad hoc network clustering method.

[0059] Such as figure 1 As shown, the cluster UAV ad hoc network clustering method provided by the embodiment of the present invention includes:

[0060] Initialize the cluster head, and the cluster head broadcasts the cluster head invitation information to the surrounding nodes;

[0061] According to the area-based division method imitating the bird flock, the cluster head divides its surrounding area, and the cluster structure in the self-organizing network composed of UAV nodes is divided into: cluster head area, node attraction area and node repuls...

Abstract

The invention provides a cluster unmanned aerial vehicle ad hoc network clustering method which can improve the stability of the whole network. The method comprises the steps that a cluster head is initialized, and the cluster head broadcasts cluster head invitation information to surrounding nodes; a surrounding region is divided by a cluster head according to a region-based division method imitating a bird flock, and dividing a cluster structure in a self-organizing network into a cluster head region, a node attraction region and a node rejection region; Wherein the nodes in the cluster head area are cluster head candidate nodes; Wherein the node attraction area comprises a gateway area and a member area, nodes in the gateway area are gateway nodes in the cluster, and nodes in the member area are member nodes in the cluster; Wherein the nodes in the node rejection area comprise idle nodes and nodes in other clusters; And when the idle node receives invitation information broadcastedby a plurality of cluster heads in a preset first time period, marking the state of the idle node according to the signal intensity of the received invitation information to complete node deployment.The invention relates to the field of unmanned aerial vehicles.

Description

technical field [0001] The invention relates to the field of unmanned aerial vehicles, in particular to a clustering method for clustered unmanned aerial vehicles ad hoc network. Background technique [0002] In recent years, mobile Ad hoe network (MANET) has attracted extensive attention from academia and industry because of its characteristics of self-organization, multi-hop transmission, dynamic topology, and distributed control. networking. MANET consists of mobile nodes that can create network topology in a dynamic environment. These nodes can move freely without using any centralized control infrastructure to achieve fast networking. Therefore, MANET is a natural disaster and emergency Ideal for emergency communications when emergency communications need to be established. [0003] With the continuous improvement of UAV's autonomous ability and intelligence level, its control method is gradually developing towards full autonomous control. A single UAV has limited ab...
