In Multi-Hop Routing identifying trusted paths through TARF in Wireless sensor networks
Journal Title: International Journal of Modern Engineering Research (IJMER) - Year 2014, Vol 4, Issue 6
Abstract
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, we have designed and implemented TARF, a robust trust-aware routing framework for dynamic WSNs. Without tight time synchronization or known geographic information, TARF provides trustworthy and energy-efficient route. Most importantly, TARF proves effective against those dangerous attacks developed out of identity cheat; the flexibility of TARF is verified through extensive evaluation with both simulation and empirical experiments on large-scale WSNs under various scenarios including mobile and RF-shielding network conditions. Further, we have implemented allow-overhead TARF module in TinyOS; as demonstrated, this implementation can be included into existing routing protocols with the little effort. Based on TARF, we also demonstrated a proof-of-concept mobile target detection application that functions well against an anti-detection mechanism.
