Abstract

The present invention provides a network node election method and node equipment, which solves the problem that more redundant nodes and a large amount of redundant system message overhead will be generated when the existing distributed clustering or connected dominance set algorithm is used for election. . The method of the present invention includes: receiving the first election information sent by the target neighbor node of the network node, the probability factor of the target neighbor node is smaller than the network probability factor; according to the first election information, determining whether the network node is a node other than the preset node , the preset node includes a DS node and a node directly communicating with the DS node; when the network node is a node other than the preset node, the second election information is sent, and the second election information includes the DS node elected by the network node . In the embodiment of the present invention, the election process is executed step by step, the information generated in the election process is fully utilized and transmitted, and the number of redundant DS nodes elected and the system overhead generated by the DS election are reduced.

Description

technical field [0001] The invention relates to the technical field of communication applications, in particular to a network node election method and node equipment. Background technique [0002] The layering of MANET is an important way to solve the scalability problem, and clustering is one of the important means to realize the layering of MANET. The efficiency of clustering algorithm directly affects the performance of MANET application system. In addition, the cluster structure formed by clustering can also provide various services of network management. [0003] In the planar structure, all nodes have equal status, so it can also be called a peer-to-peer structure; while in the hierarchical structure, the network is divided into clusters, and each cluster is composed of a cluster head and multiple cluster members. The first-level network can be divided into clusters in the higher-level network. Commonly used distributed clustering algorithms include maximum connectiv...
