An Area Localization Algorithm with Power Control for Wireless Sensor Networks

The locations of sensors in wireless sensor networks is very important for many related applications. The existing wireless sensor network localization algorithms have been analyzed.An Area Localization with Power Control (ALPC) algorithm is presented. This algorithm estimates the position of a sensor node within a certain area rather than finds the exact coordinates. The complicated calculations are done by the powerful sinks, and the sensor nodes do not have to make a lot of communications and calculations themselves, which help to save energy and then extend the life time of the network. The effects of temporal and spatial on signal model, as well as how does this affect change the localization granularity according to the measured data, are discussed. Area Naming scheme is used to reduce network traffic loads and enhance the reliability of network. At last, the the simulation result of algorithm is shown and analyzed.
