The Wireless sensor network (WSN) consisting of a large No. of sensors are effective for gathering data in a variety of environments. Since the sensors operate on battery of limited power, it is a great challenging aim to design an energy efficient algorithm which can minimize the energy consumption by sensor nodes while offering high energy efficiency and long span of network lifetime. To support high scalability and better data aggregation, sensor nodes are often grouped into disjoint, non-overlapping subsets called clusters. Clusters create hierarchical WSNs which incorporate efficient utilization of limited resources of sensor nodes and thus extends network lifetime. We proposed an algorithm for better cluster head selection based on node degree and distance from base station to reduce No. of transmissions and reduce energy consumption by sensor nodes. The proposed algorithm is compared with the HEED algorithm in terms of No. of clusters and energy consumption. Simulation results using MATLAB shows that the proposed algorithm significantly reduces energy consumption and thereby increases in the total lifetime of the wireless sensor network compared to the HEED algorithm.
