Resilient Cluster Leader Election for Wireless Sensor Networks

Free registration required

Executive Summary

Sensor nodes are often organized into clusters for efficiency and scalability purposes. Every sensor cluster is managed by a cluster leader during the network operation such as routing and data aggregation. Since managing a cluster consumes substantial energy, the cluster leader needs to be re-elected from time to time for load balancing. In hostile environments, it is critical to ensure the security of such leader election. This paper proposes an efficient, resilient, and fully distributed leader election protocol for sensor networks.
