The position of the base station (BS) in wireless sensor networks (WSNs) hasa significant impact on network lifetime. This paper suggests a mobile BSpositioning algorithm for cluster-based WSNs, which considers both the locationand the remaining energy level of the cluster heads in the network and evaluatethe performance of the algorithm under different values of network sizes,including 100m x 100m, 200m x 200m and 300m x 300m. Simulations are conductedby using OMNeT++ and proposed method is compared with two different static BSpositions, including central and external, on HEED protocol. The results showthat mobile BS performs better than both central and external BS positionsunder all network sizes. Besides, the performance difference between theproposed method and the others increases as the size of the network increases,which demonstrates that the proposed mobile BS positioning also providesscalability.
