Design and Implementation of TARF: A Trust-Aware Routing Framework for WSNs
The multi-hop routing in Wireless Sensor Networks (WSNs) offers little protection against identity deception through replaying routing information. An adversary can exploit this defect to launch various harmful or even devastating attacks against the routing protocols, including sinkhole attacks, wormhole attacks and Sybil attacks. The situation is further aggravated by mobile and harsh network conditions. Traditional cryptographic techniques or efforts at developing trust-aware routing protocols do not effectively address this severe problem. To secure the WSNs against adversaries misdirecting the multi-hop routing, the authors have designed and implemented TARF, a robust trust-aware routing framework for dynamic WSNs.
