Geographical Location-based Scheme for Sybil Attacks Detection in Wireless Sensor Networks
Wang Liang-min · Jisuanji fangzhen · 2008
Sybil attack defeats many functions of wireless sensor networks such as redundancy mechanisms, data aggregation, etc. Existing methods of Sybil attacks defense and detection have limitation. A geographical location-based scheme to detect Sybil attacks was proposed. The method constructed multi-path from event region to base station based on identities of nodes, and compared the location information of nodes in the paths to detect Sybil attacks. The simulation results show that the proposed scheme consumes less storage and lower energy, and the detection accuracy is over 95% when the channel error rate is controlled in 10%.
