An Optimal Scheduling Strategy for Wireless Resources based on Network Slicing

Abstract

Aiming at the problem that traditional wireless network resource scheduling algorithm cannot guarantee the fairness of users, cannot allocate resources to users on demand and has low utilization rate of resources in wireless network communication system, this paper introduces the concept of network slicing and proposes a wireless resource optimization scheduling strategy with the purpose of improving users’ satisfaction. Considering that each slice has different performance requirements for the radio access network, and the service difference between different slices is large, this paper selects several indicators such as data transmission rate, packet loss rate and delay to calculate the user's scheduling priority based on the analysis of the application needs of different types of business. At the same time, the slice characteristics to which the user belongs are taken as the priority measure of the user, thereby weighing the fairness and user requirements between the slices. Finally, compared with the traditional resource scheduling algorithm, the simulation results show that the proposed strategy improves the fairness of users while ensuring the throughput.
