A Mobile Ad hoc NETwork (MANET) is a dynamic wireless network that can be formed without any preexisting infrastructure in which each node can act as a router. 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 security solution that can protect MANET from various routing attacks. Different mechanisms have been proposed using various cryptographic techniques to countermeasure the routing attacks against MANET.
