Detection and Defense Mechanism against DDoS in MANET


DDoS is a serious issue and a ruthless attack in the networks that need to be detected and defended before reaching its target and causing the damage for user, data and the services. So, it is extremely important to prevent DDoS attack rather than letting it occur and then defending it. In this article we have used Reply Request (RREQ) with a thresh hold time mechanism to deal with this threat. We have used calculations and their analysis to detect the threat and the malicious node and with the help of reply request with thresh hold time we have proposed a detection technique and we can detect the malicious data source node as well. In this research we have evaluated the robustness of existing routing protocols against the malicious attacks and assess the quality and impact of security improvements and have proposed a reliable solution to handle DDoS attacks in MANETS.
