A Novel Power Tuning Anchors Localization Algorithm in Wireless Sensor Networks

Abstract

Wireless Sensor Networks (WSN) is composed of sensor nodes deployed to achieve some specific task. Localization of individual mobile node is a challenging task in wireless sensor networks. Localization system is not only for location identification but is also used as the base for routing, density control, tracking, and a number of other network aspects. In real time applications of out door or indoor environments, there are significant challenges for node localization in WSN. Keeping in view the fact that many precise and smart solutions have been proposed, a simple approach for range free localization is Concentric Anchor Beacon (CAB), which unfortunately comes with some drawbacks. Therefore, we present a solution “Power Tuning Anchors” (PTA) algorithm that outperforms in terms of accuracy. In PTA, mobile node localizes its position on the basis of minimum received power levels transmitted by the neighboring anchors. Initial simulation results have shown precision and accuracy over previously published work on localization.
