A slot assignment protocol for indoor wireless ATM networks using the channel characteristics and the traffic parameters

The rapid development of wireless in-building communication systems, has widened the scope of supported applications. Remote terminals may be capable of producing broadband real-time traffic such as variable bit-rate (VBR) video or highly bursty instantaneous file transfers. So one of the important issues in indoor broadband wireless networks (IBWN) is employment of an efficient bandwidth management protocol. In such a protocol, both the effects of radio channel behavior and the traffic heterogeneity have to be considered. In this paper we present a bandwidth allocation scheme based on the interplay of the radio channel characteristics and the traffic statistical parameters and requirements. In this scheme the base station visits the terminals in a non-uniform cyclic fashion. The intervisit interval and the amount of service which is provided to a user during each visit, is determined based on the channel and traffic parameters. This system is evaluated by simulations and is found to provide improved performance in handling the requirements of multimedia services in IBWN
