Cluster head election based on trust mechanism in wireless sensor network

Abstract

The cluster head election of current Wireless Sensor Network(WSN) mainly relies on energy and location,but ignores the trust.In this paper,using the trust as the basis of reliability and with the energy as the priority,trust value was considered to improve the system reliability.Meanwhile,an election generates more candidate nodes,every node bears cluster head in turn,so it reduces the frequency of the election and improves the efficiency of the election of cluster head.Thus,a Cluster Head Trust Elections(CHTE) based on trust and energy was proposed.The experiments show that the electing algorithm is efficient on data packet correctness of sink node and Mean Time Between Failures(MTBF) within WSN environments.
