A Novel Technique to Defend DDOS Attack in Manet

Singh N, Dumka A and Sharma R

Manet is highly vulnerable to distributed denial of service (DDOS) attacks; These DDOS attacks consume all system resources like battery power, bandwidth, energy, CPU resources, CPU cycles etc and also make resources or nodes unavailable to the legitimate users. Therefore these DDOS attacks always affect the network connectivity due to the dynamic nature of the nodes as well as functioning of the network which results in data delivery and packet dropping. Significant efforts have been made for the security of Adhoc network but it will not work always due to the dynamic behavior of nodes in the network. In this paper we will present a deep sight into DDOS attacks and how they affect the MANET, also how these attacks can be defended in the network and how we can make the network more secure by understanding the nature of attacks.
