Security Attacks in Mobile Ad-hoc Networks ? A Literature Survey


Author(s): T. Navaneethan, M. Lalli

A MANET (Mobile Ad-hoc Network) is a collection of autonomous nodes or terminals that communicate with each other by forming a multi-hop radio network and maintaining connectivity in a decentralized manner. A MANET is a most promising and rapidly growing technology and it have become a very popular research topic in recent years. Wireless networks are vulnerable to security attacks, which allows for many other forms of attacks on the networks. By providing communications in the absence of a fixed infra-structure MANETs are an attractive technology for many applications such as rescue operations, tactical operations, environmental monitoring, conferences, and the like. Security is a major concern for protected communication between mobile nodes in an unfriendly environment. MANET has no clear line of defense, so, it is accessible to both legitimate network users and malicious attackers. In the presence of malicious nodes, one of the main challenges in MANET is to design the robust security solution that can protect MANET from various attacks such as spoofing, black hole, worm hole, flooding, eavesdropping and so on. This paper provides different kinds of attacks in MANET.
