Base Station and Zone Based Performance Evaluation of Optimal Clustering in Wireless Sensor Network

The placement of base stations in wireless sensor networks affect the energy consumption for communication between sensor node and base station. In this paper we analyzed the performance of the zone based clustering protocol [2] under varying position of base stations, different zone sizes and the effect on network life time with multiple base stations. While evaluating the communication overhead of various cluster sizes, we observed that the optimal cluster size for a given network is complex, depending on a range of parameters. Simulation results show that communication overhead decreases as we increase the number of zone in the network. We show that placing multiple base stations in place of single base station in zone based routing protocol enhance the network life time.
