A Convivial Energy Based Clustering(CEBC) Solution for Lifetime Enhancement of Wireless Sensor Networks

摘要

Wireless sensor network requires robust and energy efficient communication protocols to minimize the energy consumption as much as possible. Numerous energy-based cluster head election algorithms have been proposed and implemented. However, the capacities and workloads of the neighbors of cluster heads have not been considered in large wireless sensor networks. A convivial energy-based cluster (CEBC) head selection scheme where cluster heads are elected based on the energy value of a node and the energy values of its neighbors is proposed in this paper. This is to ensure that the neighbor nodes within the one hop range of a cluster head do not drain off their energy while forwarding the data to the other member nodes, especially in large networks. Simulations in network simulator have proved that CEBC cluster head selection scheme has improved the lifetime of the network compared to the LEACH protocol.
