Abstract: In the recent years, wireless technology has tremendous rise in popularity and usage opening new fields of applications in the domain of networking. One such field concerns mobile ADHOC networks (MANET) where the participating nodes do not rely on any existing network infrastructure. Security is hard to achieve due to their dynamic nature and limitations of the wireless transmissions medium. The proposed Intrusion Detection System for ADHOC Networks system is a novel architecture that uses intrusion detection techniques to detect active attacks that an adversary can perform against the routing fabric of mobile ad hoc networks. Moreover, the system is designed to take countermeasures to attacks. The proposed system does not introduce any changes to the underlying routing protocol and operates as an intermediate component between the network traffic and the routing protocol. The system was developed and tested to operate in ADHOC On Demand Distance Vector Routing (AODV) enabled networks using the network simulator (ns-2). The system has been designed to detect resource consumption attack, packet-dropping attack and fabrication attacks.
