Performance Analysis of a Scheduler for Multiple Traffics of LTE Network

Abstract

Long Term Evolution(LTE)can support multimedia services.To guarantee the different requirements of the different services, packet scheduler plays an important role in LTE. Especially, the additional challenges are exposed to the design of scheduler when real time traffics such as VoIP (voice over IP) are transmitted over the LTE network.In this paper, a new scheduler is proposed for satisfying the different QoS requirements. This scheme distinguishes whether this connection is real time or not and give the high priority to real time traffics which are closing to time out. After scheduling allreal time traffics, delay tolerant traffics are scheduled.The performance of the proposed scheduling schemeis evaluated in terms of throughput, average delay and fairness. The result will be proofed by comparing with another LTE downlink schedulers.
