A survey of the mitigation methods against DoS attacks on MANETs

In recent years, the mobile ad hoc network (MANET) has spread to many sectors, such as education and the military. A MANET is a self-configuring and spontaneous network that is established without any administrative management and without fixed infrastructure. Due to its nature, a MANET becomes vulnerable to many attacks, and in particular, Denial of Service (DoS). DoS overwhelm the network and deprive legitimate users from using network resources. There are many methods to mitigate this attack, such as firewalls, intrusion detection systems and filtering. Each defence method has some benefits and limitations. In this paper, a description of the components of an ideal system to mitigate DoS attacks is presented which will help to design a new method to detect this attack with certainty in MANETs.
