Use of cross layer interactions for detecting denial of service attacks in WMN

Wireless Mesh Networking is an emerging technology and there are number of issues in deploying WMNs, amongst others, security is a very serious issue. In such deployments, availability poses a serious challenge. Without proper security mechanisms, networks will be confined to limited, controlled environments, negating much of the promise they hold. Due to its architecture, it suffers from various types of denial of service attacks like collision attacks, packet dropping and misdirection. Denial of Service attacks affects the availability of network and prevents legal nodes to use the network services. In this paper, we propose a framework for designing Intrusion Detection Systems to defend against denial of Service attacks. Our proposed Intrusion Detection system uses the cross layer design approach that uses information from different layers to accurately diagnose denial of services attacks.
