Wired or wireless network, security is the most crucial part of any data transmission. Securing mobile ad-hoc networks is an extremely tough issue because chances of having vulnerabilities are more when comparing to conventional wired networks. The MANET constructed by relying each node in the network. Due to the absence of central authority and dynamic topology MANET can accommodate misbehaving node as part of network. These misbehaving node or attacker fabricate different types of problems and that leads to total degradation of network performance.
