Wireless sensor networks localization with improvement in energy consumption

Using enormous number of sensor nodes has enabled WSNs to take a large area under their control. In these networks nodes are randomly distributed and have no specific information about their geographical position. But many applications and protocols require being aware of nodes localization in WSNs. Many localization algorithms have proposed radio frequency to calculate node´s position. This paper proposed a localization algorithm for wireless sensor networks which uses only one mobile station to find nodes position with high accuracy and acceptable speed. The simulation and comparison results of proposed scheme show higher performance in energy consumption and throughput in comparison of other localization algorithm. Scalability and less hardware requirement are the advantage of proposed algorithm.
