Security Issues in MANET: A Review

A Mobile Ad hoc (MANETs) is a Dynamic protocol wireless network that can be created without any pre-existing infrastructure in which each node can operate as a router. It has no fix boundaries, so it is accessible to both legitimate network users and malicious attackers. The main challenge is to design a secure solution which can protect the MANET from various kinds of security attacks. In this paper, we consider the most common types of attacks, namely snooping, rushing attack, blackhole attack, flood storm attack. ? One of the major reasons to address the security aspects in MANETS is the usage of wireless transmission medium, which is highly susceptible or vulnerable to attacks.
