Abstract

The invention discloses a circular ring model routing method based on a fuzzy C-means clustering algorithm. The problem of link stability in a mobile ad hoc network is mainly solved. The invention provides a circular ring model fuzzy C-means clustering algorithm (FCMCRR) divided by radius. In the clustering stage, a Vikor multi-standard decision is used for selecting the optimal initial clusteringcenter, and the situation that the algorithm is trapped in local optimum is avoided. In the clustering stage, a fuzzy C-means clustering algorithm is used, and the optimal classification is searchedaccording to an objective function method. An objective function considered by the invention represents a weighted distance quadratic sum from various data nodes to a corresponding clustering center,and groups of the nodes are distinguished through distances, so that a fuzzy division matrix and the clustering center of the nodes are calculated and modified. The routing strategy based on the circular ring model provided by the invention can ensure that the relay node can effectively enhance the routing performance and enhance the link stability.

Description

technical field [0001] The invention belongs to the technical field of wireless sensor networks, in particular to a clustering routing method based on fuzzy C-means and Vikor multi-criteria decision-making under a ring model. Background technique [0002] In recent years, the wireless sensor network composed of self-organized sensor nodes with strong perception ability, fast computing speed and good communication performance has attracted more and more people's attention. With the expansion of application fields, mobile scenarios have attracted the attention of researchers, and the importance of mobile ad hoc networks in monitoring and collecting environmental data has increased. Mobile scenarios consider the battlefield environment, wildlife monitoring, and dangerous environment detection. In these scenarios, all nodes are mobile, including base stations. The mobile ad hoc network is composed of mobile sensor nodes and base stations that can move in the network. The sensor...
