Modeling of distributed denial of service attacks in wireless networks

As the number of wireless users increases and as more powerful mobile devices become available for lower cost, distributed denial-of-service (DDoS) attacks will pose an increasingly real threat to wireless network security. In this paper, mathematical models are established to analyze different types of DDoS flooding traffic that could be launched in 3G wireless networks. Traffic information obtained from the model can be used to assess whether resources of a given system are vulnerable to certain types of attacks. The feasibility of launching DDoS attacks in wireless ad hoc networks is also discussed.
