针对手机病毒传播的特性,基于小世界网络模型和生物传染病微分方程模型,通过分析网络中手机的移动速度、分布密度,蓝牙信号的覆盖范围、手机病毒复制自己的时间、移动与不移动手机的比例和病毒变异等因素,建立微分方程模型,并讨论各参数对病毒传播过程的影响。仿真实验表明,该模型能较好地模拟手机病毒通过蓝牙传播的过程,对手机病毒的预测、控制和防治提供了重要的参考依据。
To reveal the law of virus spread in Bluetooth mobile phone network , a differential equation model was built on the basis of small world network model and infectious disease differential equation model .In the model, the phone move speed , phone distribution density , Bluetooth signal coverage area , the virus self-duplicating time , and the ratio of moving phone and mutation were chosen as influence factors .The influence of each parameter on the spread of virus was analyzed .The simulation results indicate that the model accords with the spread process of virus in Bluetooth mobile phone network .It provides referential support for virus prediction, control, and prevention.
