LTE Ağlarda Remote-Host ile PG-W arasındaki Kuyruk Yönetim Algoritmalarının Performans Analizi

Abstract

Mobil iletişiminin hızlı gelişmesiyle internet içeriğinin çoğu günümüzde hücresel ağlar ile sağlanmaktadır. Hücresel ağlarda yaşanan tıkanıklık sırasında kullanılan algoritmalar paket gecikmesi, kuyruk taşması ve darboğaz problemlerini çözmeye çalışmaktadırlar. LTE ağlarında remote-host ile PG-W düğümü arasındaki veri transferi yüksek hız gerektirmekte bu da hücresel ağın çalışma hızını doğrudan etkilemektedir. Doğru bir kuyruk yönetim algoritmasının seçilmesi LTE hücresel ağı için kritik bir önem kazanmaktadır. Bu çalışmada LTE ağlarında remote-host ile PG-W arasında çalışan aktif kuyruk yönetim algoritmaları olan RED, CoDel, Pie ve pFIFO’nun performanslarının, uçtan uca ortalama verim, gecikme ve paket düşürme oranları üzerindeki etkisi karşılaştırmalı olarak incelenmiştir ve sonuçları değerlendirilmiştir.

Performance Analysis of Queue Management Algorithms Between Remote-Host and PG-W in LTE Networks

Abstract

With the rapid development of the mobile communication, most of the internet content is provided by cellular networks. The algorithms used during the congestion in cellular networks try to solve the problem of queue overflow and bottleneck. In the LTE network, the data transfer between the remote host and the PG-W directly affects the operating speed of the cellular network. Choosing an active queue management algorithm is critical to the LTE cellular network. In this study, the effect of the performance of RED, CoDel, Pie and PFIFO, which are active queue management algorithms operating between Remote Host and PG-W, on LTE network on end-to-end average throughput, latency and packet dropping rates were evaluated comparatively and the results were evaluated.
