移动电话病毒的传播模型研究

对利用蓝牙进行传播的移动电话病毒传播模型进行了研究。针对移动这一重要特性，首先分析了现有模型的不足之处，通过修正Kephart和White的模型（KW模型）以及率方程模型中参数的含义得到了两个修正的模型：随机图和无标度（SF）网上移动病毒传播模型。理论和模拟的结果表明，因为移动性使带病节点和易感节点充分混和，使得模拟结果和理论模型更加接近，证实了移动环境移动速度对病毒传播的效果。

Study on modeling mobile phone virus spreading

The models of mobile phone virus that was transmitted by Bluetooth were studied in the paper. Based on the mobile property, the disadvantage of existing models was analyzed, and then two correctional models were presented by modifying definition of parameter in KW model and rate equation model. Theoretical results and simulations show that the correctional models better describe the virus spreading in mobile environment. The motion of phones better mixes infected phones and susceptible phones only, not increase infection rate of virus. The results in this paper clarify the effect of virus spreading on movement velocity in mobile environment.
