In wireless sensor networks, network security against virus propagation is one of the challenges with the applications. In severe cases, the network system may become paralyzed. In order to study the process of virus propagation in wireless sensor networks with the media access control mechanism, this paper uses the susceptible-infectious-removed (SIR) model to analyze the spreading process. It provides a theoretical basis for the development of virus immune mechanisms to solve network virus attack hidden dangers. The research shows that the media access control (MAC) mechanism in the wireless sensor network can inhibit the process of virus propagation, reduce the network virus propagating speed, and decrease the scale of infected nodes. The listen/sleep duty cycle of this mechanism will affect the suppression effect of virus propagation. The smaller the listen/sleep duty cycle, the stronger the suppression effect. Energy consumption has a peak value under specific infection probability. Meanwhile, it is also found that the spreading scale of the virus in wireless sensor networks can be effectively inhibited by the MAC mechanism.

具有媒体访问控制机制的无线传感器网络中的病毒传播

在无线传感器网络中，防止病毒传播的网络安全性是应用程序面临的挑战之一。在严重的情况下，网络系统可能会瘫痪。为了研究具有媒体访问控制机制的无线传感器网络中病毒的传播过程，本文使用易感性感染消除（SIR）模型来分析传播过程。它为发展病毒免疫机制解决网络病毒攻击隐患提供了理论依据。研究表明，无线传感器网络中的媒体访问控制（MAC）机制可以抑制病毒传播的过程，降低网络病毒的传播速度，并减少受感染节点的规模。此机制的侦听/睡眠占空比将影响病毒传播的抑制效果。监听/睡眠占空比越小，抑制效果越强。能量消耗在特定感染概率下具有峰值。同时，还发现通过MAC机制可以有效地抑制病毒在无线传感器网络中的传播规模。
