چکیده مقاله:
Locating sensor nodes is essential for many applications and protocols in wireless sensor network. Large numbers of localization algorithms have been proposed to do this. Distributed algorithms decrease communication cost while having lower accuracy. In this paper we propose a distributed method to localize sensor node using only neighboring information. Our focus is on location estimation although some ideas are also presented for implementation. Our algorithm employs an error analysis scheme and calculates expected error as well as estimated location for each sensor node. Simulation results confirm effectiveness of our scheme and prove capability of using connectivity approach.
