Future wireless systems will allow a mobileaccess to Asynchronous Transfer Mode (ATM) networks.Towards this end, one of the main problems is the management ofdifferent traffics, each of them having specific Quality ofService (QoS) requirements. This paper proposes a novelMedium Access Control (MAC) protocol coordinated by acontroller at the access point. In particular, a pollingtechnique is considered to enable cyclically the transmissions ofdifferent terminals. The maximum number of packets that eachsource can send at each cycle is regulated by a token bucketscheme. We have considered the joint management of realtime-Variable Bit Rate (rt-VBR) traffics and burstyAvailable Bit Rate (ABR) traffics. The controllerestimates the congestion of the rt-VBR buffers and accordinglyadapts the cycle order. The obtained MAC scheme, calledAdaptive Token Bucket – priority based Round Robin(ATB-RR), has permitted to achieve satisfactory QoS levels forboth rt-VBR and ABR traffics also in the presence of a scenariowith mixed real-time sources. |
