APA topology control algorithm for WSN

Abstract

This paper tackles the problem of power allocation for each node in a Wireless Sensor Network (WSN) in order to maintain active communication links on a given area. Most of previous projects have concluded that the connectivity depends exclusively on the transmission power and the number of nodes per unit area, but they normally assign the same power for every node in the network. Our work proposes APA (Adjustable Power Allocation), a wise topology control algorithm that sets the sensitivity independently for each node in the network, in order to reduce the total power consumed by the network, still maintaining 100% of the nodes connected.
