Modeling passive worm propagation in mobile P2P networks

Passive worms pose threats to mobile P2P(peer-to-peer) networks. To predict the tendency of propagation of mobile P2P passive worms and analyze their behaviors, it is necessary to model mobile P2P passive worm propagation. In this paper, the protocols of mobile P2P networks and the features of passive worm propagation are studied. On the basis, the mathematical model of passive worm propagation is proposed in applying Epidemiology. For the purpose of examining the effect of the mobile P2P-related parameters on worm propagation, simulation experiments are carried out. The results of these experiments show that different parameters have different effect on passive worm propagation, among which the average downloading rate and the average recovery rate of fixed peers have the strongest effect on passive worm propagation among mobile peers.
