Simultaneous Power Control and Power Management Algorithm with Sector-shaped Topology for Wireless Sensor Networks

In this paper, the authors propose a topology control technique to reduce the energy consumption of Wireless Sensor Networks (WSNs). The technique makes use of both power control and power management methods. The algorithm uses the power management technique to put as many idle nodes as possible into the sleep mode while invoking the power control method to adjust the transmission range of the active nodes. On the contrary to earlier works in which both of these methods were used separately, in this algorithm, they are utilized simultaneously to decide about the sleep nodes and the ranges of active nodes. It is an approximation algorithm which is called Simultaneous Power Control and Power Management algorithm (SPCPM).
