Secured Routing With Respect to Trust and Keys in Wireless Sensor Network

In the wireless sensor network, where in multi-hop routing provides least protection against identity fraud by replaying routing information. This type of defect can exploit to launch many types of harmful attacks like wormhole attacks, sinkhole attacks and Sybil attacks. This situation may be further aggregated with harsh mobile network condition. By using traditional cryptography techniques or developing some trust routing protocol does not effectively solve this problem. To provide secured routing solution for multi-hop routing in wireless sensor network need to design and implement secured and trust aware routing protocol for dynamic wireless sensor network, which does not require geographic information and time synchronization. Secured trust aware routing protocol (STRP) provides energy efficient and trustworthy routes and it also provide solutions against harmful attacks such as sinkhole, wormhole and Sybil attacks. The secured trust aware routing protocol is evaluated in both simulation and real time experiments on large scale wireless sensor network under various different scenarios.
