A New Scheme for Proactive Out of Band Signaling Solution for IP Traceback in Wireless Mesh Network

Since Wireless Mesh Networks (WMNs) have received great attention and momentum, security has become a crucial issue for them. Denial of Service attack (DoS) represents a serious threat on WMNs due to their plug-and-play architecture. Unfortunately, a DoS attack still very hard to stop due to the uncontrolled spoofing of source IP addresses. The best solution to this is to fix the problem at its root by guessing the source of attack. As a solution to this dilemma, numerous approaches have been suggested to support IP traceability. In this work, we focus on Wireless Mesh Network WMN (IEEE 802.11s standard). We design a signaling architecture, based on previous works, in order to trace anonymous IP packets back towards their source(s), where a simple security-oriented signaling protocol permits specialized signaling entities to exchange reliable signaling information that allows performing a simple and efficient traceback. This solution represents a novel and efficient approach to deal with the traceback problem in WMN environments.
