Worm Propagation Modeling Using 2D Cellular Automata in Bluetooth Networks

Bluetooth networks are envisioned to provide many promising services and applications. Meanwhile, Bluetooth networks are also increasingly becoming the target of worms. Many emerging worms can utilize the proximity of devices to propagate in a distributed manner, resulting in modeling on worm propagation substantially more challenging. In this paper, we propose an efficient Worm Propagation Modeling scheme, WPM for short. WPM utilizes the two-dimensional (2D) cellular automata to simulate the dynamics of the worm propagation process from a single node to the entire Bluetooth network. The WPM scheme integrates infection factor, which evaluates the spread degree of infected nodes, and resistance factor, which offers resistance evaluation towards susceptible nodes. Moreover, the epidemic state of each node is classified into five types in the WPM scheme, including susceptible, exposed, infected, diagnosed, and recovered. The effectiveness and rationality of the proposed model are validated through extensive simulations.
