Experimental Evaluation of a Wireless Bandwidth Management System for Multiple DASH Clients
Tiia Ojanperä, Heli Kokkoniemi‐Tarkkanen · 2016
The paper proposes enhancements to adaptive video streaming over HTTP using a wireless bandwidth management architecture. The architecture enforces distributed control over video bitrate adaptation by providing additional network-side control information to video clients in order to assist them in their decision-making. The architecture and included distributed decision algorithms are network and service aware thanks to a cross-layer signaling framework. The paper presents an MPEG-DASH based testbed implementation of the architecture and studies its performance in the context of two network-assisted video adaptation use cases. The results, obtained in an experimental evaluation conducted using the testbed, attest the benefits of the proposed solution against a state-of-the-art client-side approach.
