A Wireless Sensor Networks (WSNs) consisting of sensor with strategic locations, and a Base-Stations (BSs) whose locations are relatively flexible. A sensor cluster consists of many small Sensor Nodes (SNs) that capture, encode, and transmit relevant information from a designated area. This paper is focused on the topology of positioning process for BSs in WSNs. Heterogeneous SNs are battery-powered and energy-constrained, their node lifetime directly affects the network lifetime of WSNs. The authors have proposed an algorithmic approach to locate BSs optimally such that they can maximize the topological network lifetime of WSNs deterministically, even when the initial energy provisioning for SNs is no longer always proportional to their average bit-stream rate.
