An Improved Node Localization Algorithm for Wireless Sensor
-This paper introduces an improved localization algorithm that bases on distance and local coordinate system which is built up by beacon nodes.This algorithm evaluates the differences of several independent localization information to determine whether upgrade this node as beacon nodes according to the size of the difference whether beyond the prescribed or not.It can effectively prevent and reduce the accumulated and spread error in localization process by the audit of beacon nodes,and improve the positioning accuracy of nodes in the network.
