Review on Impact of Attacks as a Malicious Node in MANET

Abstract

The MANET is the collection of nodes which move from one place to another place and communicates with each other through wireless links. MANET is infrastructure less network having dynamic topology due to its dynamic topology network which is very susceptible to attacks. Preventing attack in MANET is a major issue. Malicious nodes in the network are the source of attacks. In MANET, there are various sorts of attacks that alter network behavior. It is the survey on impact of attacks in MANET. There are mainly two types of attacks occurring in the network data traffic attack and control traffic attacks. This paper explains different type of attacks and its impact on MANET and existing defense mechanism in MANET.
