Abstract: To better control the propagation of virus in mobile wireless sensor networks, an improved dynamics model of virus propagation was established according to the theory of infectious diseases. The dead nodes were put into the network, and the communication radius, the moving and staying states of virus nodes during the propagation process were also added. Then the differential equations were established aiming at the model, and the existence and stability of equilibrium point were analyzed. The control and extinction conditions of virus propagation were gotten. Furthermore, the effects of following factors on virus propagation in mobile wireless sensor networks were analyzed:node communication radius, moving velocity, density, immunity rate of susceptible nodes, virus detection rate of infected nodes and node mortality. Finally, the simulation results show that adjusting the parameters in the model can effectively suppress the virus propagation in mobile wireless sensor networks.

摘要: 为了更好地控制病毒在移动无线传感器网络中的传播,根据传染病学理论建立了改进的病毒传播的动力学模型。该模型不仅在网络中加入死亡节点,还增加了病毒节点在传播过程中的通信半径以及移动和停留两种状态。之后针对该模型建立微分方程组,并进行平衡点存在性和稳定性分析,得出病毒传播的控制和消亡条件,进而分析了节点通信半径、移动速度、密度、易感节点免疫率、感染节点病毒查杀率和节点死亡率等对移动无线传感器网络中病毒传播的影响。最后通过仿真实验表明,调整该模型中的参数可以有效地遏制病毒在移动无线传感器网络中的传播。
