Resilience: A Pathway Towards High Service Reliability in Telecommunication Networks

Findings, 2022
We find the loss of demands caused by a severe fault or even failure of cells in the urban telecommunication network could be compensated by two types of resilience, namely intra-sector resilience and inter-sector resilience.

Hybrid Energy Ratio Allocation Algorithm in a Multi-Base-Station Collaboration System

IEEE Access, 2019
Network densification in the 5G system causes a sharp increase in system energy consumption, a development which not only increases operating cost but also carbon emission. With the development of smart power grids, multi-source energy supply and time-of-use (TOU) power price have become effective methods for reducing system energy price (namely, total
