Multi-hop routing in Wireless Sensor Networks (WSNs) offer small protection against trickery throughout replaying routing information. A challenger can develop this defect to launch various harmful or even devastating attacks against the routing protocols, including wormhole attacks, sinkhole attacks and Sybil attacks. Even though important research effort has been spend on the design of trust models to detect malicious nodes based on direct and indirect confirmation, this comes at the cost of extra energy consumption. Conventional cryptographic techniques or efforts at mounting trust-aware routing protocols do not effectively address these problems. To secure the wireless sensor networks against adversaries misdirecting the multi-hop routing, the authors have preposed TARF, a robust trust-aware routing framework for dynamic WSNs.
