摘　　要：基于无线网络环境提出了移动节点接触频率的计算方法,对无线蠕虫的传播原理进行了分析和研究,针对节点的移动性构建了简单无线网络蠕虫传播模型(SWM)。此模型较好地显示了节点通信半径、易感节点分布密度和节点运动速度等参数对蠕虫传播的影响。仿真实验结果证明了SWM模型理论与无线网络中预测命题的一致性。该模型精确地模拟了无线网络中蠕虫的传播规律,为采取有效措施防止无线蠕虫的大范围传播提供了理论依据。In the wireless network environment,a method was proposed to calculate the contact rate of mobile nodes,and the principle of wireless worm propagation was analyzed and researched.Simple Wireless-Worm Model（SWM）,an epidemic model of wireless network worm,was constructed according to the mobility of nodes.The model properly indicates how the propagation of worm is influenced by the parameters,such as the communication radius of nodes,the distribution density of susceptible nodes,the moving velocity of nodes,and so on.The results of simulation experiment demonstrate that the SWM theory is in accord with the predicted proposition in the wireless network environment.The SWM model exactly simulates the spread process of worm in wireless networks,and provides a theoretical basis to take effective measures to prevent the propagation of wireless worms in the large-scale.
