Routing protocol for hierarchical clustering wireless sensor networks

Abstract

Energy efficient and lifetime aware wireless sensor network design is still a challenging issue in sensor network research community. Cluster based wireless sensor network is a proven approach of power aware routing. A new the challenge of cluster based approach is handling dynamic clusters, selection of cluster heads, balancing of energy consumptions of member nodes of a cluster. In this paper, we propose an energy efficient routing method for dynamic hierarchical clustering architecture WSNs with additional intra-cluster management additional subordinate cluster head (SCH) are selected in a cluster for working as data relay nodes. In our proposal, SCH nodes are selected using multilevel cluster algorithms for energy efficiency and load balancing. The proposed routing approach combines the facil-ities of proactive and reactive sensing, routing and data transmission and thus suitable for both time-sensitive and time-insensitive applications.
