A novel range based node localization in Wireless Sensor Networks

Ejaz Hussain, Xiong Zhang, Li Chao, and Sadique Ahmed Bugti
Abstract—Sensor networks are a type of communication which gives a reliable communication at a low cost. These networks have collection of components which organize themselves autonomously in the network which gives a seamless communication at low cost and in a self-organized fashion. But for achieving this goal it poses certain kinds of new concepts and optimization problems like node localization, deployment and mobility management. In this paper we are addressing one of the crucial issues namely node localization by using Token Management Vector Manipulation (TMVM). With this novel approach, we can estimate the location of deployed nodes without depending on central synchronized time reference at receivers end and at the anchors/transmitter end. Vector Manipulation (VM) gives an approach for determining the co-ordinates of unknown nodes at greater ease. Results show that this newly proposed method gives a greater accuracy in terms of average distance error on different variance of Gaussian values and performs better than synergetic localization algorithm on higher values of variance.

Index Terms—TMVM, node- localization, range based localization, vector manipulation, wireless sensor networks.
