Buffer Schemes for VBR Video Streaming Over Heterogeneous Wireless Networks

Free registration required

Executive Summary

With the co-existence of different wireless networks, which exhibit largely different bandwidth and coverage characteristics, much interest has been involved in integrating these networks to support smooth and efficient multimedia services. This paper presents an analytical framework for Variable Bit-Rate (VBR) video streaming in a two-tier wireless network with VBR channels. The authors derive the expected number of jitters and average buffering delay during video playback as measures of system performance.
