Hierarchical resource allocation strategy for RAN slices in smart grid

Abstract

With the rapid development of the new generation of smart grid, the variety of smart grid services are becoming more and more diversified, which lead to various service demands. According to different service requirements, it is necessary to allocate network resources flexibly and dynamically. In order to solve the problem of resource allocation among network slices in smart grid, we propose a two-layer dynamic resource scheduling strategy for network slicing. It can be divided into inter slice resource allocation and intra slice resource allocation. The former refers to the allocation of network resources to network slices. The latter refers to that the network slice allocates the allocated resources to the users in the slice. The simulation results show that the proposed two-layer network slicing dynamic resource scheduling strategy is superior to the current resource scheduling strategy in terms of quality of experience (QoE) of users and system throughput, which can better meet the needs of users.
