False Data Injection-Resilient Security Routing Protocol for Wireless Sensor Networks

False data injection attack and PDoS (path-based Denial of Service) attack are serious threats in wireless sensor networks. Existing schemes can effectively resist false data injection and PDoS attacks, but most of them can not find out the compromised node when the base station or sink node detect the report is invalid. In this paper, we propose a false data injection-resilient security routing protocol (FDISRP) based on bilinear pairings and different operation. The proposed protocol can resist false data injection and PDoS attacks, and if the report R is invalid, the proposed protocol can carry out the relative algorithm to find out the compromised node. The performance analysis shows that our scheme is lower in storage requirement than the others scheme, and with the number of fabricated report packet and the number of hops for report packet forwarding increasing, the energy savings significantly increasing also.
