Congestion Control and Dynamic Routing based Internet Worm Simulation

Internet worms are one of the greatest threats to the Internet. Simulation is an efficient method to study the behavior of Internet worm propagation. All the current worm simulators can not provide the dynamic changing of topology and the dynamic routing mechanism, which badly compromises the fidelity of the Internet worm simulation. This paper presents a high-fidelity packet-level Internet worm simulator, called CCDRWS (Congestion Control and Dynamic Routing based Worm Simulator). CCDRWS includes accurate congestion control and dynamic routing models, thus greatly improves simulation fidelity. Experimental results show the correctness of CCDRWS, and also the effects of the congestion control and dynamic routing models on the behaviors of worm propagation.
