A Secure and Robust Scheme to Isolate DDOS Attacks Over MANET
A Mobile ad-hoc Networks (MANETs) are self-configuring, infrastructure less networks consist of mobile nodes which communicate with one another through wireless medium. MANETs have several unique characteristics including dynamic topology, limited bandwidth and limited power of mobile nodes. Security is the biggest challenge in MANETs due to its features. The security of information of both the source and destination themselves, and the information handled by intermediate nodes, is becoming ever more important. Network security plays a crucial role in this. The traditional way of protecting the networks through firewalls and encryption software is not adequate. In this paper, we have studied the effect of different DDoS Attacks in the Ad hoc Networks. We have proposed solution that tries to eliminate the effect of these DDoS Attacks by monitoring and selection scheme using trust assignment scheme and robust random early detection scheme to isolate malicious node from the network over OLSR routing protocol. We have analysed the proposed scheme through simulation using ns2 simulator.
