Energy-Aware Enhancement of LEACH Protocol in Wireless Sensor Network

Clustering is an effective technique that can participate to entire system lifetime, scalability and energy efficiency in wireless sensor networks. Low energy adaptive clustering hierarchy protocol is a very effective protocol that enhances the network lifetime. A clustering based protocol balances the energy usage by giving equal chance to all nodes to become a cluster head. This paper presents a new algorithm to select the cluster head with increasing sensor lifetime, throughput, and the delivery packet ratio. The results show that our proposed algorithm is more efficient than previous algorithms.
