PSACCF: Prioritized Online Slice Admission Control Considering Fairness in 5G/B5G Networks
Miao Dai, Long Luo, Jing Ren, Hongfang Yu, Gang Sun

TL;DR
This paper introduces PSACCF, a heuristic algorithm for slice admission control in 5G/B5G networks that balances service priority and fairness, improving resource utilization and fairness without sacrificing priority guarantees.
Contribution
The paper proposes a novel heuristic algorithm, PSACCF, that jointly considers priority and fairness in slice admission, addressing a gap in existing research.
Findings
PSACCF achieves at least 33.6% better fairness than existing algorithms.
The algorithm maintains priority levels while improving resource utilization.
Simulation results validate the effectiveness of PSACCF in 5G/B5G scenarios.
Abstract
5G/B5G is envisioned to support various services with the assistance of network slices, each slice instance asks for adequate resources to provide the pre-negotiated service quality to its subscribers. Slice Admission Control (SAC) algorithm is a necessity for Slice Providers (SPs) to guarantee the QoS and QoE of each admitted request with limited resources. In that circumstance, the priority concern of services and the fairness of resource allocation arise as meaningful topics for researchers. The former originates from the innate characteristics of various services supported by 5G networks, and the latter matters because slices are instantiated on shared physical equipment. However, the two issues are mainly investigated separately in the literature or do not receive sufficient research simultaneously. In this work, we study the SAC problem in 5G/B5G networks, aiming at enhancing the…
