Hierarchical Resource Allocation for RAN slicing in Power Wireless Private Network

This paper presents a hierarchical slice resource sharing and allocation model for the next generation power wireless private network in multi-service and multi-scenario. The upper model is a network slice resource sharing platform, which enables the transaction of idle network slice resources between providers and requesters. Telecom operators use VCG (Vickrey-Clarke-Groves) auction ideas to determine the final price of transactions and limit the volume of transactions, to promote the utilization of idle slice resources, and improve resource utilization. The lower level allocates resources on demand, which is characterized by a more comprehensive demand dimension and low computational complexity. The simulation results show that the algorithm can be adjusted according to the actual situation to achieve dynamic resource allocation. When the resources are insufficient, it can better meet the needs of slicing and effectively improve the utilization of slicing.
