【摘要】 对于蓝牙环境下智能手机蠕虫病毒的传播,手机的移动速度是一个重要因素。假设整个网络中所有节点具有相同的速度不利于准确模拟网络动态传播特性。该文利用速度分级的方法模拟整个网络中节点速度的多样性,根据智能手机节点在蓝牙环境中的传播特性,给出蓝牙方式下的通信网络中手机节点平均度的计算方法和基于速度分段的手机蓝牙病毒传播模型。仿真实验表明,该传播模型更接近于真实环境中的手机蓝牙病毒的传播规律,能准确模拟病毒的传播过程。更多还原

【Abstract】 For Bluetooth worm propagation,a determining factor is moving velocity of smart phone in mobile environment.In some works velocity of all nodes is assumed equality.This paper adopts the method of velocity subsection to simulate the variety of nodes moving velocity in Bluetooth communication.According to the propagation characteristics of smart phone virus in Bluetooth environment,it builds an epidemic model that characterizes the propagation dynamics of Bluetooth worms based on velocity subsection.Simulation results show that the epidemic model is closer to real mobile phone network with Bluetooth communication.更多还原
