ATTACKS IN MANET

A mobile ad hoc network (MANET) is a dynamic wireless network that can be formed without any fixed and preexisting infrastructure in which each node can act as a router. In MANET, both legitimate as well as malicious nodes are there. In this paper, the current security issues in MANET are investigated. Particularly, we have examined different routing attacks, such as blackhole, impersonation, wormhole etc. These attacks are the major problem in MANET because of different factor in MANET
