  Abstract

Wireless sensor networks are becoming more widely used in various fields. Localization is a fundamental and crucial issue for sensor network operation and management. In this paper, we propose a simple, distributed and low cost localization algorithm which approaches the benefits of ranging-free schemes. The proposed algorithm utilizes the location information of neighbor anchor nodes to estimate an estimative area which has the unknown node inside. Then, by using RSS (Received Signal Strength)-comparison, it compares the RSS of received signals from the neighbor anchor nodes and reduces the estimative area. Simulation results show that our proposed algorithm is more accurate and stable than the traditional CPE (Convex Position Estimation) algorithm which has the same approach.
