Abstract :
Location estimation is one of the most attractive applications in wireless sensor networks. In this paper, we propose a new iterative location estimation method using radio signal strength indicators (RSSIs) not only among target and fixed nodes but also among target nodes. Our computer simulation shows that, if the RSSIs among target nodes are available whose locations are unknown so should be estimated, we can improve the location estimation performance by means of the proposed iterative method
