Implementation of Trustable Routing Framework for WSNs

Abstract: Recently use of Wireless Sensor Network Becomes Greater; there is little protection in Wireless sensor Networks (WSNs). In WSN the multi-hop routing against identity misdirecting through replaying routing information is also not secure. An Attacker can exploit this flow to launch various harmful or even destructive attacks against the routing protocols, like sinkhole attacks, wormhole attacks and Sybil attacks. The situation is further critical by mobile and harsh network conditions. Earlier cryptographic techniques or efforts at developing trustable routing protocols do not effectively address this severe problem. To secure the WSNs against attacker misdirecting multi-hop routing, we have designed and implemented Trustable Routing Framework for WSN, TRF provides trustworthy and energy- efficient route. Most importantly, TRF proves effective against those harmful attacks developed out of identity deceptions; the resilience of TRF 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 are implementing a low-overhead TRF module in Tiny OS. This implementation can be incorporated into existing routing protocols with the least effort.
