Hierarchical Auction and Dynamic Programming Based Resource Allocation (HA&DP-RA) Algorithm for 5G RAN Slicing

The emerging fifth generation (5G) wireless system will have different requirements in terms of rate, latency and reliability. Network slicing which addresses the deployment of multiple logical networks as independent business operations on a common physical infrastructure has attracted more attentions. However, problems such as isolation and resource allocation of wireless network slices still exist. The paper focuses on the allocation of spectrum resources for 5G RAN slices. Firstly, The hierarchical auction model can satisfy both inter-slice isolation and intra-slice customization. Then, we propose a Hierarchical Auction and Dynamic Programming based Resource Allocation (HA&DP-RA) algorithm to allocate resources for the slices. The dynamic programming algorithm is adopted to obtain a stable solution. Finally, simulation results show the effectiveness of the proposed scheme.
