Energy Efficient Positioning of Base Station in Clustered WSN

Abstract

In order to enhance the energy efficiency of Wireless Sensor Networks, large number of protocols have been developed in the last two decades. Clustering is one of these proposed solutions. These protocols mostly exploit the cluster head selection criteria, network topology, number of hops, and heterogeneity. In this paper, we analyse the effect of base station position with respect to the sensing field for increased network stability period, lifetime and throughput. Our analytical findings are supported by experimental results for square shaped and circular sensing field. Our findings suggest that, if we have flexibility to position base station as per our choice then it should be placed at the center of the sensing field.
