THROUGHPUT ESTIMATION BASED ON LAST SEGMENT AND SMOOTH THROUGHPUT

Abstract

Video transmission over HTTP protocol is being and will be widely used in
applications of online video streaming in electronic devices. However, one of
the video streaming requirements is guaranteeing the best QoS for users by
adjusting the parameters of video timely according to the variation of
throughput. Therefore, the problem of throughput estimation for improving
the quality of service is an important problem which has been studied around
the world. There have been many studies on the throughput estimation,
which are Last segment throughput and Smooth throughput, but each
algorithm has its own advantages and disadvantages. This paper will give the
idea of building a new algorithm that combines the advantages of the two
over algorithms to achieve a buffer stable and less volatile video bitrate.
Simulation results demonstrate the effectiveness of the new algorithm to
improve the quality of services.
