A Distributed Secured Localization Scheme for Wireless Sensor Networks

摘要

Nowadays, location-aware security policies play a key role in wireless sensor networks. In this paper, we propose to develop a distributed secured localization scheme that validates the reliability of location information associated with event reports.We make the anchor nodes are deployed such that they form connected sensor coverage and their routing information to these anchor nodes, thereby avoiding the sink overload problem. Since this scheme involves distributed anchor nodes for verification, it has less overhead and delay. By simulation results, we show that our proposed scheme attains good delivery ratio with reduced delay and overhead.
