Security is a weak link of network systems. The malicious usage and attacks have caused tremendous loss by impairing the functionalities of the computer networks. In an attempt to enhance security in MANETs many researchers have suggested and implemented new improvements to the protocols and some of them have suggested new protocols. Existing MANET routing protocols, such as Ad-hoc On-demand Distance Vector routing protocol (AODV), do not provide enough security defense capacity. Distributed Denial of Service (DDoS) attack has become a major problem to networks.
