Localization based on received signal strength has been a topic of Interest due to its relative simplicity in measurement and minimal hardware requirements. Much of the research in this field has been on developing an indoor propagation model. A generic indoor propagation model has largely been unsuccessful due to the complex multipath environment present in indoor environments. The main focus of this study is to find the position of the target when the estimated distance from the measurement points are known. The straightforward approach to this problem is by using trilateration techniques. A novel weighted centroid based method is introduced and its performance is compared to the different trilateration techniques.
