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.
