Abstract

Smart grid actively combines the characteristics of 5G with large bandwidth, low delay and large connection to realize full coverage IOT in complex environment of 5G smart power plant. Firstly, this paper proposes the system architecture of Internet of things based on 5G power plant scenario. Then, focusing on the energy hole problem in sensor networks, MCLESC protocol is proposed. The protocol uses an improved adaptive immune algorithm to plan the mobile base station's moving trajectory based on the minimum energy consumption of data packet, and selects the cluster head from the high-energy nodes to improve the network's lifetime and stability. Based on four simulation scenarios, this paper compares the simulation results of different protocols through the network lifetime, the number of packet transmission, the number of cluster head sensor nodes and other indicators. We can see that MCLESC protocol can effectively improve network life and reduce network energy consumption.
