Abstract

Abstract: According to the uneven distribution of the unknown node in wireless sensor networks，a new self-adaptive localization algorithm in Wireless Sensor Networks is proposed.In order to get a reasonable distribution of beacon node，this paper divides the area by traversal the unknown beacon，then changes the virtual force coefficient of beacon node.The location accuracy is improved by this algorithm.The theory analysis and experimental results show the feasibility and effectiveness of the algorithm.
