Packet drop (grayhole/blackhole) attack is occurs at a network layer to discard the packets in MANET. It is essential to detent and prevent this attack for improving performance of network. This article provides the packet drop attack detection and prevention using RBDR (Rank Based Data Routing) for AOMDV routing protocol. The fields of RBDR are generated with routing information and analysis behavior of network for detecting the malicious paths. The scheme is to identify the malicious paths for preventing the packet drop attack and also able to find the trusted multiple disjoint loop free routes for data delivery in MANET. The simulation is conducted in NS2 using AOMDV reactive routing protocol and analyze with packet loss delivery, average end-to-end delay and packet delivery ratio. The proposed technique can reduce the effect of packet drop attack.
