Evaluating video streaming over UWB wireless networks

Abstract

Video streaming is going to drive the Internet to a new height. However, how to distribute the high-quality video streams that are already delivered to the doorsteps of ordinary customers to almost all rooms in their dwellings still remains a technique challenge. There are various proposals for wired, ``no-new-wires" or wireless approaches, but their performance in real environment is yet to be examined. In this paper, we evaluate the performance of high-quality video streaming over short-range wireless networks, specifically Ultra-Wide Band (UWB), for a two-tiered broadband home network. Our analysis and experiment results reveal the unique features of UWB reservation schemes and their intrinsic throughput-latency tradeoffs, which indicates the efficacy of UWB for high-speed, in-room wireless access with both quality and mobility provisioning.
