摘要：Heterogeneous wireless networks expand the network capacity and coverage by leveraging thenetwork architecture and resources in a dynamic fashion. However, the presence of differentcommunication technologies makes the Quality of Service (QoS) evaluation, management, andmonitoring of these networks very challenging. Each communication technology has its owncharacteristics while the applications that utilize them have their specific QoS requirements.Although, the communication technologies have different performance assessment parameters,the applications using these radio access networks have the same QoS requirements. As aresult, it would be easier to evaluate the QoS of the access networks and the overall networkconfiguration depending on the performance of applications running on them. Using suchapplication-based QoS evaluation approach, the heterogeneous nature of the underlyingnetworks and the diversity of their traffic can be adequately taken into account. In this paper,we propose an application-based QoS evaluation approach for heterogeneous networks.Through simulation studies, we show that this assessment approach facilitates better QoSmanagement and monitoring of heterogeneous network configurations.
