Abstract

This paper presents the node localization under Non-Line-of-Sight conditions in wireless sensor networks. Consider the static blind sensor and mobile anchor nodes are in random deployment. Each of the sensor nodes determines its own position by itself is called localization. Obstacles blocking between the direct paths, called as Non-Line-Of-Sight (NLOS), which causes NLOS error. The propagation of this error results in unreliable localization and significantly decreases localization accuracy. It is an important research topic because position information is a major requirement in many WSN applications. Localization algorithms are used to find the position information of nodes in wireless sensor networks (WSNs). In the proposed work, Range Map Stitching (RMS) algorithm is used. This method can provide good localization accuracy and energy efficiency by mitigating the effects of NLOS measurements.
