摘要
在移动自组网(MANET)中,针对节点的移动性导致网络拓扑结构动态变化的特点,利用微分方程提出MANET中的病毒传播模型,并对构建的微分方程系统进行平衡点存在性和稳定性分析,得出病毒传播的阈值及消亡条件,从而进一步研究节点移动速度、通信半径、免疫成功率和免疫失效率对MANET中病毒传播的影响。选取相应的实验参数,对系统进行仿真实验,结果验证了实验仿真与理论分析的一致性。
In Mobile Ad Hoc Network（MANET）,aiming at the characteristics that node mobility leads to dynamic network topology changes.So the MANET virus propagation model is proposed with differential equation,and on the equilibrium existence and stability analysis,constructed differential equation system is also conducted.The threshold and demise conditions of the virus transmission are determined,and further effects of node moving speed,communication radius,immunization success rate and immune failure rate on virus transmission in MANET are also studied.Experimental parameters are selected for system simulation,and the results verify the consistency of the experimental simulation and theoretical analysis.
