摘　　要：针对无线传感器网络病毒变异,异常节点检测技术不能实施对异常节点检测和定位的问题,提出一类SEIQRV-Type模型。通过对模型进行理论分析,得到网络病毒的传播阙值R 0,验证了平衡点的稳定性,研究节点感染率、E-I状态节点转移率、感染节点隔离率、节点免疫率、病毒查杀率、通信半径和节点上(下)线率等参数对无线传感器网络中病毒传播的影响。仿真结果验证了理论分析的正确性,通过动态调节参数可以有效控制病毒在无线传感器网络中的传播。Aiming at the problem that the abnormal node detection technology cannot implement the detection and location of abnormal nodes due to virus mutation in wireless sensor networks,a SEIQRV-Type model was proposed.Through theoretical analysis of the model,the transmission threshold R 0 of network virus was obtained,which verified the stability of the equilibrium point,and the effects on virus propagation in wireless sensor networks of parameters such as the node infection rate,E-I status node transfer rate,infection node isolation rate,node immunity rate,virus killing rate,communication radius and node adding rate or removing rates were studied.Simulation results verify the correctness of the theoretical analysis,and the propagation of viruses in wireless sensor networks can be effectively controlled by dynamically adjusting parameters.
