摘　　要：为了深入研究病毒在具有MAC机制且拓扑不同的无线自组织网络中的传播特性,采用基于拓扑特征的病毒传播模型,分别对节点数量为2000的随机网络、无标度网络、LEACH网络中有或无MAC机制时的病毒传播特性进行了仿真和分析。结果表明:MAC机制能够抑制无线自组织网络中病毒传播的速度和规模;当网络拓扑不同时,其MAC机制的抑制强度也会不同,相比较而言,簇团结构最不利于MAC机制抑制作用的发挥;在相同网络环境下,无标度网络的安全性最好,LEACH网络的安全性最差。研究结果对无线自组织网络中病毒传播的防范具有指导意义。In order to further study the spreading characteristics of viruses in mobile ad hoc networks with MAC mechanisms and different topologies,a virus spreading model based on topological characteristics was adopted to simulate and analyze the spreading characteristics of viruses in random network with the node number of 2000,scale-free network and LEACH network with or without MAC mechanism.The results show that MAC mechanism can inhibit the speed and scale of virus spreading in mobile ad hoc networks.The suppression intensity of MAC mechanism is different with various network topologies.Comparatively speaking,the cluster structure in the network is the most detrimental to the MAC mechanism inhibition.With the same network environment,scale-free network has the best security,and LEACH network has the worst security.The research results have guiding significance for the prevention of virus transmission in mobile ad hoc networks.
