Mobile Ad Hoc Networks (MANETs) are self organized networks whose nodes are free to move randomly while being able to communicate with each other without the help of an existing network infrastructure. Ad hoc on-demand distance vector routing (AODV) is demand driven one of the best and popular routing algorithm. AODV is severely affected by well-known black hole attack in which a malicious node injects a fake route reply message that it has a fresh route towards destination. In this paper, a novel approach is proposed that makes a modification in existing AODV routing protocol. A novel approach finds the safe route between sending and receiving node. The simulations show that the proposed approach is efficient than normal AODV with high packet delivery ratio and throughput.
