Cross-layer IDS for Rushing attack in Wireless Mesh Networks

Abstract

Wireless Mesh Networks (WMNs) are a promising technology to provide the wireless internet connectivity. WMNs are becoming a popular choice for wireless internet service providers to offer internet connectivity as it allows a fast, easy and inexpensive network deployment. However, security in WMNs is still in its infancy. Security and privacy has been a major concern in WMNs. WMNs are susceptible to broad variety of attacks due to its open medium, dynamic topology and lack of physical security. WMNs are more vulnerable in Network layer. Several attacks are possible in the network layer. Some of the attacks have possible solutions but there is no solution for to detect Rushing attack which leads to the Denial of Service. In this paper, the authors proposed Cross-Layer Intrusion Detection System (CLIDS) for Rushing attack. We evaluated the performance of our technique using network simulator 2. Simulation results show that CLIDS has less false positive and false negative rates than single layer intrusion detection system.
