Location information is of paramount importance for Wireless Sensor Networks (WSN). The accuracy of collected data can significantly be affected by an imprecise positioning of the event of interest. Despite the importance of location information, real system implementations, that do not use specialized hardware for localization purposes, have not been successful. This paper proposes a location estimation scheme that uses a probabilistic approach for estimating the location of a node in a sensor network. The localization scheme makes use of additional knowledge of topology deployment. The paper assumes a sensor network is deployed in a controlled manner, where the goal of the deployment is to form a grid topology.
