In designing the routing protocols for Wireless Sensor Networks, clustering is one of the methods used to manage network energy consumption efficiently.LEACH is one of the most famous clustering mechanisms. It elects a cluster head based on probability model. This approach may reduce the network lifetime because LEACH does not consider the energy remains of each node. In this paper, we present an unequal cluster-head selection mechanism algorithm. Simulation results demonstrate that the proposed algorithm has higher efficiency and can achieve better network lifetime and energy consumption.
