Dynamic epidemic model of smart phone virus propagated through Bluetooth and MMS

Recent occurrences of mobile worm spread way like Comm Warrior on smart phone has created growing concerns. This kind of worm is capable of spreading through both Bluetooth and MMS. According to the propagation characteristics of Bluetooth and MMS, we divide the phone node into S, E, I, R, D states and 11 kinds of state conversions. We build the SEIRD model of smart phone virus for the Bluetooth and MMS hybrid spread mode and further discuss the influence of the propagation parameters such as coverage radius of Bluetooth signal, distribution density of smart phone, moving velocity of smart phone, the time for worm to replicate itself and user gather density in groups on the spread of virus. Simulation results show that this model simulates the virus spreads for the Bluetooth and MMS hybrid spread mode perfectly.
