Embodiment Construction

[0055] 1) The present invention considers the mobility of the nodes, the size of the cluster and the energy of the nodes, comprehensively considers the factors, and is beneficial to the stability of the cluster. Based on the purpose of the present invention is to improve the stability and balance of the cluster, so the priorities of attention to the three factors are different. In order to adapt to the dynamically changing topology of mobile ad hoc networks, the mobility of nodes is the primary consideration. Secondly, the size of the cluster determines the number of cluster heads in the network. When clustering, it is hoped that the size of each cluster is roughly the same, so that the load of the cluster heads can be balanced. If the cluster is too small, the throughput of the nodes in the cluster will be improved, but the throughput of the entire network will be reduced; if the cluster is too large, the throughput of the nodes in the cluster will drop sharply, becoming a bo...

Abstract

The invention provides a method of clustering the moving ad hoc network based on the state mechanism, belonging to the wireless communication field in the communication technology. The method respectively grades three factors of the mobility of the node, the size of the cluster and the energy of the node, combines the three factors and puts forward a node state mechanism. According to the node state, two kinds of node identities of Register and Guest are prescribed, and a cluster head, backup cluster heads and cluster members from the nodes of Register identity are selected; while from the nodes of Guest identity, the nearest cluster members are selected as the access points, which join the corresponding cluster through two jumps. The invention is superior to the traditional method in respects of the average survival time of the cluster and the balance degree of the cluster, and improves the performance of the network.

Description

technical field [0001] The invention takes the mobile self-organizing network as the research object, designs a clustering method based on the state mechanism, and belongs to the wireless communication field in the communication technology. Background technique [0002] A mobile ad hoc network is a network composed of a group of mobile nodes with wireless transceivers. It does not depend on preset infrastructure and can be quickly built anytime and anywhere. Each node can move freely, and has the function of a router, helping other nodes establish communication links through multi-hop forwarding. [0003] There are two main architectures in mobile ad hoc networks: flat structure and hierarchical structure. The status of each node in the plane structure is equal, and the communication between nodes is completed through mutual cooperation. The biggest disadvantage of this structure is poor scalability, and the control overhead increases sharply with the increase of network ...
