The rapid development of wireless in-building communication systems, haswidened the scope of supported applications. Remote terminals may be capableof producing broadband real-time traffic such as variable bit-rate (VBR)video or bursty data transfers. Consequently one of the important issues inindoor broadband wireless networks (IBWN) is employment of an efficientbandwidth management protocol. In such a protocol, both the effects of radiochannel behavior and the traffic heterogeneity have to be considered. Inthis paper we present a bandwidth allocation scheme based on the interplayof the radio channel characteristics and the traffic parameters andrequirements. In the proposed scheme the base station visits the terminalsin a non-uniform cyclic fashion. The inter-visit interval and the amount ofservice which is provided to each user during a visit, is determined usingthe channel and traffic parameters based on an analytical approach. Thissystem is evaluated by simulations and is found to provide improvedperformance in fulfilling the requirements of multimedia services in IBWN.
