Active Worm Propagation Model with Discrete Time

Active worms spread in an antomated fashion and can flood the Internet in a very short time. Modeling the spread of active worms can help us understand how to monitor and defend against the propagation of active worms effectively. In this paper, we present an active worm propagation model with discrete time, referred to as Discrete Time Worm Propagation (DTWP), which considers the propagation of anti-worms. The figure of simulation by matlab indicates that compared with the AAWP model, our DTWP model can characterize the latter propagation of active worms more effectively.
