Prevention of Routing Attacks using Trust-Based Multipath Protocol

: In order to provide secure data transmissions, the neighbour nodes must recognize different types of attacks and their effects on the Mobile Ad Hoc Networks (MANET). To perform routing in the traditional protocol the number of hops is used to select the route. To measure the neighbour’s behaviour, to forward the packets, and to reduce the effect of malicious node trust model is used in MANET. In this paper, Trusted Path-based ad hoc on-demand multipath distance vector (TAOMDV) routing protocol is proposed. It is used to discover trustworthy forward paths and can prevent the blackhole, wormhole, flooding and misrouting attacks. The highest trusted path is selected to send the data. The above said attacks are prevented, by the TAOMDV, using passive acknowledgement. The simulation result shows that TAOMDV protocol achieves high packet delivery ratio (PDR), reduces the packet overhead and end to end delay of packet. It provides higher detection ratio of the attacker. But the throughput is achieved little lower while more attackers presents in the network.
