Bandwidth Map-TCP friendly rate control algorithm for improving QoS in streaming applications

Abstract

In Wireless Wide Area Network (WWAN), QoS are important, especially in Multimedia applications like Skype calls. The Internet is today facing a change of the traffic type dominating the aggregates at network core and edges. Interactive VoIP and videoconferencing are currently having an exponential growth of usage. To dynamically determine the appropriate streaming bit rate and quality, the server needs to closely track the underlying bandwidth conditions. Several such rate control algorithms have been proposed for streaming application. These algorithms are reactive in nature, in that, they monitor the video play out buffers or certain end-to-end network parameters and adapt streaming rate depending on the changes in the observed values. This paper analyzes the performance of Bandwidth Map-TCP Friendly Rate Control (BW-MAP-TFRC) algorithm for improving QoS in streaming applications using different performance indices and then relatively compares the results available from these indices.

“…In [7] and [8] the idea of building the "bandwidth map" is put forward to enhance the QoS in highly mobile environments [22]. Through the use of these maps, based on information collected in the past, one can expect the available bandwidth in a given geographical point, calculated as an average historical value, and as a consequence dynamically determine the most suitable bit rate for encoding video streaming.…”
