| Summary: | This paper investigates the performance of
exponential/proportional fair (EXP/PF) and maximum-largest
weighted delay first (M-LWDF) scheduling algorithms in the
third generation partnership project long term evolution
(3GPP LTE) providing packet-switched multimedia services.
It, then, identifies a suitable packet scheduling algorithm on a
basis of their performance evaluation. The performance
evaluation is conducted in terms of system throughput, average
real time (RT) and non-real time (NRT) throughput, packet
loss for RT service and fairness for NRT service. A video
streaming traffic is used to model the RT service, while a webbrowsing traffic is modelled for NRT service. Simulation
results show that at lower load M-LWDF algorithm provides
better performance than EXP/PF while as the load increases
the EXP/PF gives better performance. |
