摘要： 基于MIPv4网络环境，构建一种新型蠕虫——MIPv4-Worm，给出MIPv4节点接触频率的计算方法，对MIPv4网络中蠕虫的传播策略进行了分析和研究，建立MIPv4网络蠕虫传播模型(MWM)。该模型显示了各参数对蠕虫传播的影响。MIPv4-Worm传播的仿真实验表明，该模型较好地模拟了MIPv4网络中蠕虫的传播规律，为采取有效措施防止MIPv4中蠕虫的大范围传播提供了理论依据。

Abstract: In Mbile IPv4(MIPv4) networks environment, it presents MIPv4-Worm, a new type of worm, and a method is presented to calculate contact rate of MIPv4 nodes. In MIPv4 networks, it analyzes and resarches the propagation strategy of worm. It establishes MIPv4-Worm Model(MWM), an epidemic model of MIPv4 networks worm. The model preferably shows how parameters influence propagation of worm. Simulation experiments of MIPv4-Worm propagation show the model can simulate the spread process of worm correctly in MIPv4 network, and provides a theoretical basis to take effective measures to prevent the propagation of MIPv4 worm in the large-scale.

Key words: MIPv4 network, MIPv4 nodes, network worm, worm propagation model
