摘要：A mobile ad hoc network (MANET) is a system of wireless mobile nodes that can generously and dynamically self organize into arbitrary and temporary topologies without the need of any preexisting communication infrastructure. While many challenges need to be resolved before the large scale use of MANET, one particular area of concern is the routing, where one important role is security. A black hole is a malicious node that incorrectly replies for any route requests without having active route to specified destination and drops all the receiving packets. If these malicious nodes work together as a group then the damage will be very serious. The key concept of the existing solution is that, to use modified AODV routing protocol by introducing data routing information table (DRI) where as watchdog method detects misbehaving nodes by maintaining a buffer that contains recently sent packets
