Abstract

The optimal placement of base stations in a two tiered wireless sensor network (WSN) can reduce the energy consumption of sensor nodes (SN) and thus can improve network lifetime. In our paper, we address the base station location problem and provide a geometrical solution introducing a new concept called node partitioning technique. An algorithm based on the geometrical approach is also provided in the paper.
