Performance Evaluation of Enhanced EXPRULE Scheduler for LTE Multi Cell Network

Abstract

Nowadays, the demand for high data rate in the Long Term Evolution (LTE) network
is rapidly increasing. The vast deployment of real-time services in LTE network increases
rapidly. To support such demand, beside the vast update from 3G to 4G, LTE network
implements several techniques such as handover and scheduling techniques to support the
Quality of Service (QoS) requirements for UEs. One of the challenges in LTE network is the UEs
mobility management. The services to UEs shall remain stable while the UEs are moving from
one cell to another. In this paper, we analyzed the performance of the proposed eEXPRULE
scheduler for LTE network in multiple cell scenario while the UEs are randomly move from one
cell to another with different speeds. Extensive simulations are carried out using LTE-Sim
simulator. The proposed eEXPRULE improves the performance of video traffic. It improves the
video throughput (16%), video PLR (50%), video delay, VoIP delay (62%), and spectrum
efficiency over the existing schedulers.
