Detection and Reaction against DDoS Attacks in Cellular Networks

The scarcity of resources in wireless communications and the experience of attackers in conducting Denial of Service (DoS) and Distributed DoS attacks in Internet make detection and reaction against these attacks in cellular networks, particularly in the 2.5G and 3G cases, a challenging issue to address. CODERA (Cooperative DEtection and Reaction Architecture) is our proposed architecture that aims to detect and react against DDoS and save network's availability to legitimate users. This paper depicts CODERA's components and operations and analyzes its performance.
