We propose a performance improvement scheme of location estimation using received signal strength (RSS) method in wireless sensor networks. Reference nodes in sensor networks receive RSS from a target node whose location is unknown, calculate the RSS deviation score, and eliminate the scattered RSS of edge-score. This improves the estimation accuracy which is not high in RSS methods in general. The simulation results show that the proposed scheme enables better location estimation than the conventional scheme under the small number of pre-RSS measurement situations.
