Abstract
The multi-hop routing in wireless sensor networks (WSNs) will provide little safe against identity deception through replaying routing information. This may be create various dangerous attacks against routing information, attacks such as Sinkhole attacks, Wormhole attacks and Sybil attacks. These types of attacks cannot completely remove from network through our traditional cryptographic technique. In order to secure wireless sensor networks from various attacks through misdirecting multihop routing, I have design and implement TARF, for dynamic WSNs, a robust trust aware routing framework is used. This trust aware routing framework does not depends upon the accurate time synchronization or distribution of nodes within the sensor network. This TARF will provide trust worthy and energy efficient routing path in wireless sensor network. Mostly TARF proves effective against those harmful attacks developed because of identity deception through replaying routing information. Further, I implement a TARF in TinyOS, and verified through Network Simulator.
