A New RSS-based Wireless Geolocation Technique Utilizing Joint Voronoi and Factor Graph.

This paper proposes a new joint received signal strength (RSS)-based Voronoi and factor graph (RVFG) wireless geolocation technique. The RSS-based Voronoi (RV) technique is used to provide the initial position for the RSS-based factor graph (RFG) technique. The initial point obtained by the RV is used to select the appropriate four monitoring spots which are covering the target for the RFG. We also modify the RV so that it can be performed in the fusion center. The proposed technique is tested in outdoor environment where only path-loss is taken into account. The performance of the proposed technique in term of the root mean square (RMSE) is compared to that of the conventional RV only technique. The results show that the accuracy of the proposed technique outperforms the conventional RV technique. The material in this paper was presented in part at Asia Modelling Symposium, Kuala Lumpur, September 2015 [1]. [ABSTRACT FROM AUTHOR]
