Abstract

This paper presents a novel algorithm for localization in wireless sensor networks utilizing a fuzzy inference system at each sensor node. The algorithm using fuzzy distance measuring based on received signal strength information (RSS). The advantage of employing the RSS information is that no extra hardware is needed for localization. The simulation results and indoor experiments demonstrate that the proposed scheme employing fuzzy logic system can localize the mobile sensor nodes with certain accuracy.
