Sensor networks are collection of sensor nodes which co-operatively send sensed data to base station. Clustering in Wireless Sensor Networks (WSNs) is an important technique to ease topology management and routing. Clustering provides an effective method for prolonging lifetime of a WSN. The different clustering algorithms also differ in their objectives. This paper proposes energy efficient clustering schemes for wireless sensor networks. Clustering sensor nodes into small groups is an effective method to achieve scalability, fault tolerance, load balancing, routing etc. The simulation results demonstrate the effectiveness of proposed protocol in term of energy and routing overhead.
