Study of bandwidth estimation on wireless networks for DASH
Vu Van-Huy, Tein-Yaw David Chung · 2017
Wireless Multimedia service is very important as mobile handsets are widely used. To reach all users readily, video streaming on HTTP gets popular as HTTP is supported almost in any existing platforms. Dynamic Adaptive Streaming over HTTP (DASH) represents a great standard for multimedia services in Internet. In order to offer better user experience and cope with dynamically varying network conditions, a big challenge is to estimate precisely next segment bandwidth, which is a significant premise in determining next multimedia bitrate. This paper investigates the effectiveness of exiting bandwidth estimation schemes and our presented MACD based Bandwidth Estimation Scheme (MBES) in wireless environment. The simulation results show that when the network bottleneck is on the backbone network, MBES can perform well and is superior to other existing scheme although not as well as that in the wired network.
