Securing Wireless Sensor Networks by Using Location Information
2009
Security is a major concern in wireless sensor networks deployed in hostile environments. If the physical locations of the nodes are known, such information can be used as an aid in the detection of potential attacks and identification of intruders. The purpose of this paper is twofold: first, we survey some defensive techniques for sensor networks based on localization; then, we show how some concepts of robust statistics can be adopted to solve the problem of localizing a node in the presence of malicious beacons.
