Multiple TFRC Streaming in a WiMAX Environment

Employing multiple TFRC connections has emerged as a promising lightweight way of coping with wireless channel losses in a congestion-controlled tandem network. This work extends multiple TFRC connection streaming to broadband uplink streaming. This study differs from earlier work for a number of reasons: it reports on a specific wireless technology, IEEE 802.16 (WiMAX); it considers the impact on buffer management at the subscriber station rather than at the Internet end; and it considers actual delivered video quality and not simply network statistics. In terms of video quality, it is reported that multiple TFRC connection streaming has a role to play provided there are only a few connections opened at any one time. Therefore, the work demonstrates that multimedia services can be achieved over broadband wireless by multiple TFRC connection streaming.
