Sensor Location Verification Scheme in WSN
摘要
Abstract
Locations of sensor nodes are an important contextfor the sensed data. Self-localization isone of the most essential technologies in WSNs. Since most current sensor localization schemesrely on location information that is provided by beacon nodes,reliability of the locations provided by beacon nodes becomes criticaltothe quality of net-workservice. Beacons drifting and malicious beacons lead to decline accuracy of sensor localization. A lightweight and distributedReputationbasedLocationVerificationscheme(RLV)is proposed. In our proposed scheme,we can i-dentify unreliable beacons by establishing a comprehensivereputationmodel based on mutual observations of sensor nodes. Extensive simulation results show that the reputation model can reflect the accuracy of nodes position authen-tically. And RLV can detect more than 95% of unreliable beacons.关键词
