Performance Analysis of Trust-Aware Routing Framework for Wireless Mesh Networks
Journal Title: International Journal of Modern Engineering Research (IJMER) - Year 2013, Vol 3, Issue 5
Abstract
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, we have preposed TARF, a robust trust-aware routing framework for dynamic WSNs. Without prolonged time synchronization or known geographic information, TARF offers dependable and energy-efficient route. TARF demonstrates effective adjacent to those harmful attacks developed out of identity trickery; the flexibility of TARF is verified through extensive assessment with both simulation and observed experiments on large-scale WSNs under various scenarios including mobile and RF-shielding network conditions. We have put into action a low-overhead TARF module in TinyOS; this implementation can be included into existing routing protocols with the least effort. Based on TARF, we also verified a proof-of-concept mobile target detection application that functions well next to an anti-detection mechanism.
