Adaptive Multiservice Resource Allocation Algorithm With Wireless Network Virtualization

초록

Wireless network virtualization (WNV) is emerging as a new paradigm to provide high speed communications and it is identified as one of the key enabling technologies to bring fifth-generation (5G) networks into fruition. With network slicing, physical networks are partitioned into multiple virtual networks to serve different types of service while satisfying their specific requirements. In this study, we present an adaptive spectrum control scheme for the WNV technology. Particularly, we develop a two-tier resource allocation algorithm to utilize a multi-service wireless network. In order to increase flexibility and independence among different network slices, our proposed approach is decoupled into two level bargaining games. These games are designed to solve the inter and intra slice resource allocation problems while ensuring traffic services with multiple requirements. Using four different bargaining solutions, we provide considerable benefits when network agents successfully cooperate and maintain an optimal performance balance. Simulation results and analyses are provided to reveal the effectiveness of our proposed approach compared with existing WNV based spectrum control protocols. Finally, we address some challenges and identify research areas for future studies.
