Co-SRL: A Convex Optimization Algorithm for Anchor Localization in Wireless Sensor Networks

Abstract

This paper proposed a Convex Optimization method which is called Co-SRL and is used to localize sensor location in Wireless Sensor Networks.Co-SRL can be used to help the node to localize a friendnode or mobile node using anchors. In Co-SRL, convex optimization algorithm is used forthe estimationof malicious nodeposition.Simulation result shows that Co-SRL is both secure and robust, in an environment without colluding, Co-SRLcan identify more than half of the malicious nodes; and in an environment with colluding, no more than 15% of malicious nodescan escape from the identification of our methods.
