Paper Abstract:
|
Bluetooth is a short-range wireless interconnect that in its 2.0 version has sufficient capacity to support encoded video streaming, possibly from an Internet access point. The default setting of the Automatic Repeat Request (ARQ) facility leads to poor quality video, as streaming is delay-sensitive. The paper introduces an adaptive algorithm that alters the number of ARQ retransmissions according to buffer fullness, which is used to indicate both buffer congestion and radio frequency channel conditions. This is a necessary but not sufficient requirement for quality video at the receiver. In an extension to the cross-layer approach, the number of retransmissions is made sensitive to picture importance. Delivered video quality is demonstrated to be consistently high. |
