An intelligent target localization in wireless sensor networks

Recently, wireless sensor networks (WSNs) has been widely recognized as a promising technology in latest development in green buildings communications. Localization is one of the fundamental issues in wireless sensor networks. The accuracy of estimated positions can be significantly helpful to use in an intelligent e-applications. In this paper, we propose a fast and efficient localization scheme based on RSSI model for wireless sensor networks. The node locations are computed by performing simple geometric calculations that rely on the broadcasting information from a mobile beacon equipped with GPS. Simulation results show the node positions can be determined accurately and our proposed scheme outperforms previous well known localization schemes.
