Quality-focused resource allocation for resilient 5G network

The upcoming 5G cellular wireless network brings new challenges and problematic issues in providing services with different quality of service (QoS) requirements and serving huge amount of mobile devices in a spectrum-efficient manner. 5G-based systems will combine macrocells, different type of small cells and heterogeneous networks. As a result of this combination, a 5G-based network will feature a sophisticated multi-layered architecture, and a proper resource allocation will become a major challenge for it. A reliable provision of services as well. In this paper, the analysis of the impact of different QoS schedule algorithms (Round Robin, Best CQI and PF) to the allocation of resources and a reliability of data transmission in 5G network was carried out. Also, the relation of QoS characteristics (BER, data loss) to the perceptual evaluation of service quality by the end user in different ways of the resource allocation on 5G network was investigated also. The perceptual evaluation of a service quality, known as Quality of Experience, was investigated using mean opinion score method.
