Abstract:
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.
