Intrusion Detection and Prevention Systems in MANET

What are ADHOC networks? MANET means Mobile Ad hoc Network - the Collection of mobile nodes that dynamically form a temporary network for communication within the nodes. This network has the capability to configure itself every time when a mobile node changes its location. This type of network has attractive features such as its low transmission power to conserve energy, increase throughput, and reduce delay. However, it suffers from many constraints, including limited resources, and the use of insecure wireless communication channels. Hence any type of intruders can attack the communication at any time, especially the routing mechanism between the nodes. Unattended installation of sensor nodes in the environment causes many security threats in the Ad-hoc networks. The security of the DSR and AODV protocol is vulnerable to different types of attacks. The base research by Dubey et.al [3] developed an intrusion detection and prevention system on AODV protocol. This research had a major drawback that it allowed a packet loss of minimum 5 to 6% which is quite high and also the methodology increased the energy consumption in network thereby reducing the lifetime.
