Abstract: We propose a new epidemic model of mobile phones Bluetooth virus through studying the spatial characteristics and mobile features of the mobile nodes.Combined with human mobility patterns,a method was presented to calculate the average degrees of mobile nodes.The possibility of Bluetooth virus outbreak was analysised with percolation theory.Two important parameters,including the distribution densities of nodes,the proportion of Bluetooth contact were introduced in the model.Simulation results show that the model can simulate the spread process of Bluetooth virus between mobile phones correctly,which accords with the virus propagation rules.
