A method for distributed section networking in wireless sensing network

Abstract

The utility model discloses a distributed cluster-based network construction method for the wireless sensing network. Via nodes, the method exchanges information in a neighborhood scope and obtains partial network information, on the basis of which the nodes are calculated in a weighed way to get the weighed value for competitive cluster head, and then the cluster head is selected and clusters are formed to put an end to the cluster formation of the network. The invention brings the partial network information that is commanded by the nodes into full play, and obtains the weighed value of the most competitive cluster head in a weighed way, thereby realizing the most cluster-based optimization of the network and the load balance of the system. The nodes weighed value of the invention is a dynamic change in the cluster-based process, and a more optimized cluster-based result is accessible. Compared with the prior cluster-based network construction method, the invention has the advantages of easy realization of load balance, the elongation of network survival period and better performance, meets different requirements of different application circs on network performance, and has relatively good adaptability and extensibility.
