Scheduling algorithm for multiclass services in LTE network

Abstract

Quality of service (QoS) requirements have paved the way to a great deal of research about scheduling and resource allocation mechanisms. The fairness and throughput maximization have been considered as classical techniques. These techniques fail to fit with different QoS requirements over the Long Term Evolution (LTE) systems. These QoS requirements are presented in the form of scheduling priorities, delay budgets, etc. To handle service class requirements in LTE network, this paper suggests a new scheduling algorithm entitled Multiclass Scheduling Algorithm (MuCSA) that deals with QoS requirements, relying on the multiclass systems. Simulation results show that our scheduling algorithm outperforms existing algorithms in terms of the system throughput, delay and fairness.
