Analysis of DDoS Attack Effect and Protection Scheme in Wireless Mobile Adhoc Network

In Wireless Mobile Ad hoc NETworks (MANET) every node functions as transmitter, router and data sink is network without infrastructure. Detecting malicious nodes in an open ad-hoc network in which participating nodes have no previous security associations presents a number of challenges not faced by traditional wired networks. Traffic monitoring in wired networks is usually performed at switches, routers and gateways, but an ad-hoc network does not have these types of network elements where the Intrusion Detection System (IDS) can collect and analyze audit data for the entire network. A number of neighbour-monitoring, trust-building, and cluster-based voting schemes have been proposed in the research to enable the detection and reporting of malicious activity in ad-hoc networks.
