中文摘要：病毒传播是无线传感器网络(Wireless Sensor Network,WSN)安全领域的一个重要问题。传统关于WSN中病毒传播的研究大多基于同质网络进行,很少考虑网络结构的异质性对病毒传播的影响。为了探究网络结构的异质性对WSN病毒传播效果的影响,分别进行了相关理论分析和仿真实验。首先,利用平均场理论建立了静态同质和异质WSN上的SIR病毒传播模型,计算得到了两种网络的传播阈值,结果显示,在网络规模足够大时,异质WSN的传播阈值等于0,而同质WSN的传播阈值大于0,且异质WSN的稳态感染比例要大于同质WSN,说明异质WSN更有利于病毒的传播。其次,对同质WSN和异质WSN中的病毒传播过程进行了仿真,仿真结果与理论分析结果一致,仿真结果还显示,网络的异质性越高,越有利于病毒的传播。

外文摘要：The spread of virus is an important problem in the security of Wireless Sensor Networks(WSN).Most of the traditional studies on virus transmission in WSN are based on homogenous networks,and the impact of the heterogeneity of network structure on virus transmission is seldom considered.In order to explore the influence of the heterogeneity of network structure on the effect of virus transmission in WSN,theoretical analysis is performed and simulation experiments are carried out.Firstly,the SIR virus propagation models of static homogeneous and heterogeneous WSN are established based on the mean-field theory,and the propagation thresholds of the two networks are calculated.It is found that when the network scale is large enough,the propagation threshold of heterogeneous WSN is equal to 0,while the propagation threshold of homogeneous WSN is greater than 0,and the steady-state infection ratio of heterogeneous WSN is greater than that of homogeneous WSN,indicating that heterogeneous WSN is more conducive to the spread of the virus.Secondly,the virus propagation in homogeneous WSN and heterogeneous WSN is simulated.The simulation results are consistent with the theoretical analysis.In addition,the simulation results also show that the higher the heterogeneity of the network,the more conducive to the spread of the virus the WSN.
