Bandwidth Allocation for VBR Video in Wireless ATM Links

This paper presents a medium access level VBR bandwidth allocation scheme for wireless ATM (WATM) networks. After introducing a wireless ATM system model and the associated dynamic TDMA/TDD medium access control (MAC) scheme, an algorithm for VBR slot allocation is proposed. The algorithm combines information from User Parameter Control (UPC) at the call admission control (CAC) level with rapid MAC level estimates of the requirements for each VBR virtual circuit (VC). The method described is applicable to both conventional VBR and recently proposed VBR+ in which UPC parameters are dynamically renegotiated as source bit rate requirements vary. Simulation experiments using statistically multiplexed MPEG-1 video are carried out for a typical 25Mbps dynamic TDMA/TDD wireless ATM access link scenario. Experimental results show that, for the VBR video under consideration, the proposed scheme can achieve throughputs in the range of 60–70% while maintaining reasonable QoS.
