Wireless Sensor Networks (WSNs) are one of the most important distributed networks which are used in the wide range of applications. Energy is one of the major limitations of wireless sensor networks, which has direct impact on the network's life time. LEACH protocol is one of the most well-known clustering schemes that select cluster heads randomly. Clustering is an effective topology control Approach in wireless sensor networks. In this paper, the authors proposes new clustering algorithm that using an imperialist competitive algorithm to select cluster heads in LEACH algorithm.
