Abstract Wireless Sensor Network (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 also provides the base for routing, density control, tracking, and a number of other communication network aspects. In real time applications of outdoor 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, an approach for range free localization is Concentric Anchor Beacon (CAB), which comes with the requirement of improvement. In this paper, we have presented a novel 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. Localization error, anchor density, radio range and Gitter between two consecutive power levels are the performance metrics used for evaluation of PTA. Initial empirical results have shown better precision and more accuracy in terms of aforementioned performance parameter.
