Abstract

This paper presents a Medium Access Control (MAC) protocol for broadband wireless LANs based on the ATM transfer mode, together with the evaluation of its performance in terms of throughput and access delay. Important characteristics of the MAC protocol are the way information between the Mobile Stations (MS) and Base Station (BS) is exchanged and the algorithm used to allocate the bandwidth in order to support the service categories. The performance is heavily influenced by the way the BS is informed about the bandwidth needs of the MSs. In order to obtain an efficient system, a contention resolution scheme based on an Identifier Splitting Algorithm combined with polling is proposed for that purpose, in case no piggybacking can be used. A detailed analytical evaluation, both on cell level and higher layer packet level, is performed, leading to an assessment of the efficiency and the access delay of the system.

支持ATM业务类别的无线ATM网络MAC协议的性能评估

提出了一种基于ATM传输模式的宽带无线局域网介质访问控制(MAC)协议，并从吞吐量和接入延迟两个方面对其性能进行了评价。MAC协议的重要特征是移动站(MS)和基站(BS)之间交换信息的方式以及用于分配带宽以支持服务类别的算法。性能在很大程度上受到BS了解ms带宽需求的方式的影响。为了获得一个高效的系统，提出了一种基于标识符分割算法和轮询相结合的争用解决方案，以避免不能使用捎带。在单元级和更高层分组级上进行了详细的分析评估，从而对系统的效率和访问延迟进行了评估。
