Embodiment Construction

[0030] see figure 1 A method for clustering a mobile ad hoc network according to an embodiment is provided, including the following steps:

[0031] S100: Obtain the remaining energy of the node, the original energy of the node and the number of neighbor nodes of the node.

[0032] In order to improve the stability of the clustering method, the remaining energy and node degree of the node are considered, the energy information of the node can be obtained through the energy management unit, and the neighbor node information can be obtained through the information exchange between nodes, and the individual of the neighbor node of the node can be obtained. number.

[0033]S200: Obtain the broadcast information packet sent by the neighbor node to the node, obtain the speed, direction and position of the neighbor node according to the broadcast information packet sent by the neighbor node to the node, and obtain the speed, direction and position of the neighbor node according to th...

Abstract

The invention relates to a clustering method and system of a mobile ad hoc network. According to the clustering method and system, nodes are grouped, nodes in the same group satisfy a preset mobility condition, so that it can be ensured the nodes in the corresponding groups can have similar mobility, and therefore, the stability of clustering can be improved; the residual energy parameter values of the nodes, the node degrees of the nodes and the mobility parameter values of the nodes are calculated; the stability factors of the nodes are calculated; nodes corresponding to maximum stability factors in the groups are adopted as cluster heads; non-cluster head nodes in the groups are added into clusters where corresponding cluster heads are located; the nodes in the mobile ad hoc network are traversed, non-cluster head nodes which have not been clustered are clustered separately; and therefore, network node clustering can be realized. When the stability factors are calculated, the mobility parameter values of the nodes, the residual energy of the nodes and the node degrees of the nodes are all considered, and therefore, the cluster heads which are selected according to the stability factors of the nodes are optimal nodes with the mobility, residual energy and node degrees of the nodes considered; after the cluster heads are obtained, the non-cluster head nodes are clustered; and therefore, network clustering stability can be improved.

Description

technical field [0001] The invention relates to network optimization technology, in particular to a clustering method and system of a mobile ad hoc network. Background technique [0002] At present, the research on the background of mobile ad hoc network (MANET) is carried out extensively. The mobile ad hoc network is a new type of frameless mobile network. It uses wireless communication technology and forwards through nodes to realize the internal nodes of the network to move freely in the network and maintain communication. With the development of mobile networks, people's demand for mobile service information content and form increases, and the proportion of mobile data services and multimedia services in communications is increasing. The self-organizing and node mobility characteristics of the mobile ad hoc network enable rapid deployment independent of existing networks and other facilities, and can be widely used in the construction of military battlefield information...
