Optimal Clustering in Zone Based Protocol of Wireless Sensor Network

The placement of base stations in wireless sensor networks affect the coverage of sensor nodes and the energy consumption from communication. 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. We show that placing multiple base stations in place of single base station in zone based routing protocol enhance the network life time.
