WiMAX中保证QoS的跨层架构研究

Abstract

Abstract:

This paper proposes one novel cross-layer architecture for quality of service(QoS) of guarantee in point-to-multipoint (PMP) Worldwide Interoperability for Microwave Access (WiMAX) networks, which divides the whole protocol structure model into two sub-planes vertically: one is data service flow delivery sub-plane which could provide data processing and delivering layer-by-layer for service flow based on IEEE 802.16 standards, and the other is the QoS resource management sub-plane which could coordinate the operation of all manage modules in different protocol layers and implement adaptive QoS joint control by various signaling. Simulation results show that the QoS joint control solution based on the cross-layer architecture can provide guarantee of QoS for multimedia communication service flow effectively and obtain users' fairness when comparing to the typical control solution used in PMP WiMAX.

Key words: worldwide interoperability for microwave access(WiMAX), cross-layer design, quality of service(QoS), signaling, joint control
