A Secure Intrusion Detection System against DDOS Attack in Wireless Ad-Hoc Network Using Multi-Hop Routing Algorithm.

MANET (Wireless Mobile Ad-hoc Network) is a technology which are used in society in daily life an\ud activities such as in traffic surveillance, in building construction or it’s application is used in battlefield also. In\ud MANET there is no control of any node here is no centralized controller that’s why each node has its own\ud routing capability. And each node act as device and its change its connection to other devices.\ud The main problem of today’s MANET is a security, because there is no any centralized controller. Our main aim\ud is that we protect them from DDOS attack in terms of flooding through messages, packet drop, end to end delay\ud and energy dropping etc. For that we are applying many techniques for saving energy of nodes and identifying\ud malicious node and types of DDOS attack and in this paper we are discussing this technique
