摘　　要：随着智能电网系统中移动终端的增加,其对传输数据低时延、大带宽和高可靠性的需求尤为紧迫。为解决其中无线传输、信息处理和可靠性不足等问题,文章采用“切片分组网(sliced packet network,SPN)+可信无线局域网(wireless local area network,WLAN)”通信新技术网络架构,建立多种移动终端设备安全无线传输和计算任务卸载的总时延优化卸载模型,提出一种基于交替优化技术的算法。仿真结果表明,该策略不仅保证设备安全高效地接入网络,还可显著降低传输时延,具有优异的成本效益。With the increase of mobile terminals in the smart grid system,the demand for low latency,large bandwidth,and high reliability of transmission data is particularly urgent.To solve the problems of wireless transmission,information processing,and lack of reliability,“sliced packet network(SPN)+trusted wireless local area network(WLAN)”communication network architecture is adopted,and a total delay optimization offloading model for secure wireless transmission and offloading of computational tasks for multiple mobile terminal devices is established,and a model based on alternating optimization model is proposed.The simulation shows that this strategy not only ensures safe and efficient access to the network but also significantly reduces the transmission delay,which has excellent cost-effectiveness.
