Mobile Ad hoc Network is the kind of wireless networks that utilize multi-hop radio relaying and it is an infrastructure less Network due to its capability of operating without the support of any fixed infrastructure. Security plays a vital role in Mobile Ad hoc NETwork (MANET) due to its applications like battlefield or disaster-recovery networks. Current wireless research points out that the wireless MANET has more security problems than traditional wired and wireless networks. MANET is severely affected by Distributed Denial of Service (DDoS) attacks which becomes a problem for users of computer systems connected to the Internet. MANETs are more vulnerable compared to wired networks due the lack of a trusted centralized authority and limited resources.
