Wireless sensor networks are composed of large number of power constrained nodes, which needs an energy conservation protocols to reduce the energy consumption as much as possible. Clustering is a standard approach for achieving efficient and scalable performance in wireless sensor networks. Motivated by the former research of clustering algorithm, this paper is to study an energy efficient algorithm called multihop-LEACH. The two main concepts of this protocol are intra-cluster multihop communication and inter cluster multihop communication.
