摘　　要：信息物理系统(Cyber-Physical System,CPS)是通信网络将信息系统与物理系统无缝连接的高度复杂系统。由于无线通信信道的广播特性,传感器通过无线通信网络将观测数据发送到远程状态估计器时会遭遇拒绝服务(Denial-of-Service,DoS)袭击的干扰。针对通信范围有限的传感器在发送数据时需要基于中继的协作通信网络,从干扰者角度研究了基于终端估计误差的能量效率问题。通过建立基于信道选择和能量分配的混合整数规划模型,推导出目标函数的显性表达式,进一步通过提出最优干扰策略的必要条件设计出使能量效率最大化的算法,仿真实验验证了所提算法的有效性。Cyber-Physical System(CPS)is a kind of highly complex system that utilizes communication network to connect information system and physical system seamlessly.The sensor would encounter Denial-of-Service(DoS)attack when sending the observation data to the remote state estimator through wireless communication network,because of the broadcast characteristics of wireless communication channel.Based on the necessity that relay-based cooperative communication networks are required for sensors with limited communication range to forward data,the energy efficiency problem based on terminal estimation error is investigated from the perspective of jammer.Firstly,a mixed integer programming model is established based on channel selection and energy allocation.Then,the explicit expression of the objective function is derived,and the algorithm for maximizing energy efficiency is presented by proposing the necessary conditions of optimal jamming strategy.Finally,the effectiveness of the proposed algorithm is verified through simulation experiments.
