Wireless Video Streaming QoS Guarantees Based on Virtual Leaky Bucket

With recent rapid advances in wireless communication and networking, the demand for wireless video streaming is exploding. Unlike data streaming, video streaming is much more challenging due to unique characteristics such as bursty flow, stringent delay bound, and selective loss tolerance. Under the dynamic nature of wireless channels, wireless video streaming is virtually impossible to achieve deterministic Quality-of-Service (QoS) guarantee. Recent development in statistical QoS guarantees has shown great potential for wireless video streaming. However, in the case of statistical QoS guarantee, loss of data due to queue length bound violation or delay violation is often inevitable.
