The multi-hop routing in Wireless Sensor Networks (WSNs) highly vulnerable against identity cheating through replaying routing data. An attacker can uses this drawback to launch various serious or even disturbing attacks against the routing protocols, like sinkhole attacks, wormhole attacks and Sybil attacks. The situation is further forced by mobile and unkind network conditions. Old cryptographic techniques or efforts at developing trust-aware routing protocols do not effectively address this serious problem. To secure the WSNs against attackers misdirecting the multi-hop routing, the authors have designed and implemented TARF, a robust trust-aware routing framework for dynamic WSNs.
