异构网络的QoS评估:基于应用的方法

QoS Evaluation of Heterogeneous Networks: Application-based Approach

Farnaz Farid, Seyed Shahrestani, Chun Ruan

摘要:

本文提出了一种基于应用的异构网络QoS评估方法,通过异构无线网络体系结构,可以动态扩展网络容量和覆盖范围。然而,由于存在不同的通信技术,这种类型的网络架构的服务质量(QoS)评估是非常具有挑战性的。不同的通信技术具有不同的特性,并且利用它们的应用具有独特的QoS要求。虽然通信技术具有不同的性能测量参数,但是使用这些无线电接入网络的应用具有相同的QoS要求。因此,基于在接入网络上运行的应用的性能来评估接入网络的QoS和整体网络配置将是更容易的。使用这种基于应用的QoS评估方法,可以充分考虑底层网络的异构性及其流量的多样性。通过模拟研究,我们表明,基于应用性能的评估方法,有利于更好的QoS管理和异构网络配置的监控。

英文摘要:

In this paper, an application-based QoS evaluation approach for heterogeneous networks is proposed.It is possible to expand the network capacity and coverage in a dynamic fashion by applying heterogeneous wireless network architecture. However, the Quality of Service (QoS) evaluation of this type of network architecture is very challenging due to the presence of different communication technologies. Different communication technologies have different characteristics and the applications that utilize them have unique QoS requirements. Although, the communication technologies have different performance measurement parameters, the applications using these radio access networks have the same QoS requirements. As a result, it would be easier to evaluate the QoS of the access networks and the overall network configuration based on the performance of applications running on them. Using such application-based QoS evaluation approach, the heterogeneous nature of the underlying networks and the diversity of their traffic can be adequately taken into account. Through simulation studies, we show that the application performance based assessment approach facilitates better QoS management and monitoring of heterogeneous network configurations.
