A Novel Acknowledgement based Intrusion Detection System for MANETs
Journal Title: International Journal of Modern Engineering Research (IJMER) - Year 2014, Vol 4, Issue 9
Abstract
In Mobile Ad Hoc Networks(MANETs), a set of interacting nodes should cooperatively implement the routing functions to enable end-to-end communication along dynamic paths composed by multi-hop wireless links. Several multi-hop routing protocols have been proposed for ad hoc networks, and most popular ones include: Dynamic Source Routing (DSR), Optimized Link-State Routing (OLSR), Ad Hoc On-Demand Distance Vector (AODV) and Destination- Sequenced Distance-Vector (DSDV). Most of these protocols rely on the assumption of a trustworthy cooperation among all participating nodes; unfortunately, this may not be a realistic assumption in real hosts. Malicious hosts could exploit the weakness of MANET to launch various kinds of attacks. Node mobility on ad hoc network cannot be restricted. As results, many Intrusion Detection System(IDS) solutions have been proposed for the wired network, which they are defined on strategic points such as switches, gateways, and routers, can not be implemented on the MANET. Thus, the wired network IDS characteristics must be modified prior to be implemented in the ad hoc network. Thus an IDS should be added to enhance the security level of MANETs. If MANET can detect the attackers as soon as they enter the network, we will be able to completely eliminate the potential vulnerabilities caused by compromised nodes at the first time. IDSs usually act as the second layer in MANETs. This paper presents an novel IDS for MANETs which is based on acknowledgements.
