The Architecture Design and Evaluation Method for Eco-Sustainabability Oriented Next Generation Communication Networks

The rapid development of communication technology and the arrival of the era of internet of everything not only aggravate the deployment of communication infrastructure and energy consumption intensively, but also bring potential impacts to network security and electromagnetic environment. Therefore, the discussion of the 6th generation of mobile communications system (6G) network architecture should transfer its focus from network performance and user experience into all-round sustainability of the networks. Based on the traditional networks, the paper explores an eco-sustainable network architecture for 6G, discusses its construction framework from multi-level, and analyzes the dynamic interaction between 6G networks and the real physical world. Considering the evaluation demands of networks' sustainability, a new comprehensive evaluation system for new network architectures is designed. Aiming at the challenge of multi-dimensional and cross domain sustainability analysis of networks, an evaluation method of communication networks based on machine learning is proposed, so as to provides a reference for the construction and optimization of the ecological sustainability of the networks. © 2020, Editorial Department of Journal of Beijing University of Posts and Telecommunications.
