This paper deals with the Radio Resource Management (RRM) layer of future broadband systems capable to realize a wireless access to Asynchronous Transfer Mode networks. The interest here is in designing an efficient scheme operated by an access point to integrate demanding traffics, such as high-quality real-time video and interactive Web traffics. We adopt a time division multiple access air interface and we propose an original solution where a medium access protocol and a usage parameter control technique jointly define the radio resource management. In particular, we use a cyclic assignment scheme with a novel traffic policer based on fuzzy logic for video sources and on a token-bucket scheme for Web sources. Our technique is named Fuzzy Logic-Based Multiple Access (FLBMA) to remark the central function of the fuzzy policer. The FLBMA performance, derived through simulations, has highlighted the following interesting results: (i) very high capacity of video traffic sources in comparison with alternative RRM schemes; (ii) fair service of different traffic sources; (iii) video traffic Quality of Service independent of Web traffic load.
