An effective localization algorithm based on received signal strength

Efficient tracking schemes are becoming very important due to the increasing availability of wireless networks and the importance of location information for applications such as vehicle and object tracking, surveillance, military uses etc. This paper presents a simple approach based on the measurements of the received signal strength to determine the position of wireless nodes. An estimation algorithm, using range measurements from multiple, scattered, beacon transmitter stations with known locations, is presented that lowers position location inaccuracies, has relatively low complexity and uses only the local information. Various simulation results are presented that demonstrate the performance of the algorithm.
