Research on Self-Localization Algorithm of Wireless Sensor Networks
The technology of self-location is one of the key technologies of WSN. Based on the idea of two hop distance calculation in the Euclidean theory, a novel theory of graded circle position estimation for WSN is proposed in this paper. In the graded circle position estimation, the precision of nodes are divided into 8 ranks, and the nodes which rank is higher than 5 can be promoted as the reference nodes assisting the other unknown nodes self-localization, and the circulatory adjustment can improve the precision of position estimate. In order to validate the validity and veracity of graded circle position estimation, OPNET network simulation soft is used in this paper.
