A Cloud-Edge Collaboration Framework for Power Internet of Things Based on 5G networks

In order to make full use of the advantages of 5G networks and meet the requirement of communication performance by the massive growth of devices in the area of power Internet of things, it is necessary to study the collaborative working mechanism of edge computing and cloud computing and give solutions. Based on the communication characteristics of 5G networks, this paper constructs a cloud-edge collaboration framework for Power Internet of Things, and comprehensively judges the information communication process according to communication bandwidth, communication delay and reliability of information, for example selecting large bandwidth or low delay or both of them, processing at the edge or in the cloud, so as to reduce the cost of data storage, communication and processing, promote the utilization rate of 5G networks communication resources to achieve customization and maximum utilization. In this paper, through the combination of cloud modeling analysis and edge real-time decision-making, the five-tuple of task processing type and four-tuple of communication information type are defined, and the cloud edge collaborative communication method of two-level cooperation between edge and sensor equipment and between edge and cloud communication is proposed to achieve high-quality, high-performance, real-time communication for improving the efficiency of power terminals.
