An Efficient Scheme to Prevent DDoS Flooding Attacks in Mobile Ad-Hoc Network (MANET)

摘要

The purpose of this study is to understand the flaws of existing solutions to combat the DDoS attack and a novel scheme is being provided with its validation to reduce the effect of DDoS attack in MANET Environment. As Internet users are increasing day by day, it is becoming more prone to attacks and new hacking techniques. People are accessing information and communicating with each other on the move. Mobile Ad-hoc Network (MANET) is responsible for this rapid change in the lives of people. With the emergence of technology, where people communicate or share important documentations on the go with the help of laptops, PDAs, notebooks, smart phones etc., the loopholes in the Internet security have also increased and they are becoming more difficult to handle due to the characteristics of MANET such as dynamic topologies, low battery life, multicast routing, frequency of updates or network overhead, scalability, mobile agent based routing and power aware routing, etc. The network is becoming more prone to attacks like DDoS, byzantine, resource consumption, blackhole, grayhole, etc. Therefore, there is an urgent need to look into the security issues to allow authorized users to access the information available on Internet without any risk. In this study, a novel scheme is proposed which deals with suppressing the influence of the attack. The effectiveness of the approach is validated with simulation in GloMoSim, integrated with parsec compiler, on a windows platform.
