Pin Point Localization Technique in Commercial Areas Using Wireless Sensor Network

Wireless Sensor Networks (WISENETs) support variety of collaborative applications such as monitoring, tracking and surveillance. Different applications demands different granularity of location information. Thus, localization is really become an important challenge in wireless sensor networks. Although, many localization techniques [2, 3, 4, 5, 11, 10] have been developed, but all of them have certain limitations like size, cost, energy efficiency, power constraints and extra hardware requirement. In this paper, we propose a Pin Point Localization Technique using virtual coordinate system to solve the problem of localization in wireless sensor network. This technique provides accurate position of an object without any cost or extra hardware requirement. Thus, the technique is energy efficient and more successful in indoor places where techniques like GPS are failed to determine the exact location.
