Enhanced Unequal Clustering Algorithm for Wireless Sensor Networks

Clustering is considered as solution for more energy conservation during communications in wireless sensor networks. Recently, a new clustering algorithm named Unequal Clustering Algorithm (UCA) is proposed to avoid the burdened cluster-heads located around the sink due to the traffic coming from others which are far to the base station. This paper presents an Enhanced Unequal Clustering Algorithm called EUCA. This solution reduces the control traffic during a clustering process by eliminating the competition of nodes to become cluster-head and allows a better reactivity to event. Simulation result shows that EUCA conserves more energy.
