While routing Wireless Sensor nodes in the Multi-hop network ,nodes may undergo some attacks such as sink hole attack, worm hole attack, Sybil attack etc., by the attackers through identity deception. So, to secure WSN’s against attackers or hackers misdirecting the nodes in the network while routing, in our base paper we have designed and implemented TARF, a robust trust aware routing framework concept for dynamic for WSN’s. TARF provides trustworthy and energy-efficient route and also it provides security against all these attacks which are mentioned above. In our work, we are using modern technology like ECC i.e., Elliptic Curve Cryptography for encoding and decoding purpose. To know the performance of this TARF routing, in our paper we are comparing TARF Routing with Existing Routing and generating routing tables. To find the secure network discovery we are generating Combinatorial Key for Pre Key-Distribution in TARF Network. In the handheld devices like mobile we are trying to find the attacker information.
