Reference Architecture for End-to-End QoS in Heterogeneous Wireless Network Environments |
The first step in providing end-to-end QoS in a wireless network is to model the current environment and identify the state of the art in QoS methods. The paper provides a reference architecture for end-to-end QoS in heterogeneous wireless network environments by giving an overview of the reference architecture and showing a detailed end-to-end session establishment including the necessary communication between service and transport layer. To estimate and compare the complexity of QoS signalling, an appraisal of the QoS signalling effort is given.
