Abstract

This paper proposes a new joint received signal strength (RSS)-based Voronoi and factor graph (RVFG) for wireless geolocation technique. The RSS-based Voronoi (RV) geolocation technique is used to select the appropriate four monitoring spots of RSS-based factor graph (RFG) covering the target. The RV technique is also used to provide the initial position of RFG technique. We modify the Voronoi geolocation algorithm so that it can be performed in the fusion center. The performance of the proposed technique is compared in term of the root mean square (RMSE) to that of the conventional Voronoi only technique. The results show that the accuracy of the proposed technique out performs the conventional RV technique. © 2015 IEEE.
