In recent days Mobile Ad-hoc Network (MANet) has drawn the attention of many researchers largely owing to the inherent characteristics and varied applicability. Unlike traditional wired network, MANet has no clear line of defense. Moreover, the intrinsic properties of MANet expose many nontrivial security challenges. Security is of the prime concerns for network designers in any network. But for MANet, which allows both legitimate network users and malicious attackers to access the network, security issues have been a permanent concern because of the open shared wireless link and nomadic nature of nodes.
