Trilateration and Multilateration Based Localization of Wireless Devices

Abstract

Many new techniques for localization of wireless sensor networks have been developed in the past few decades, the most popular of which is multilateration – a simple technique that determines the position of one node or sensor in space using data collected from other nodes or sensors in the same network. In this paper, we propose a new localization algorithm based on multilateration, named as ‘Moving Point Algorithm’, which logarithmically searches the space to determine the location of a given node in the sensor network. The simulation of out algorithm shows that it outperforms traditional multilateration by means of localization accuracy and percentage of localized nodes.
