A Receiver-driven Adaptive Mechanism Based on the Popularity of Scalable Sessions



Receiver-driven adaptation allows streaming of multimedia content to different receivers across heterogeneous networks. However, receivers are only encouraged to adapt if network providers guarantee a fair distribution of bandwidth and also the punishment of receivers that do not adjust their rate in case of congestion. We define a receiver-driven adaptive mechanism based on a new fairness protocol that provides the required guarantees for adaptation. We use simulations to evaluate the proposed mechanism and to compare its performance with other receiver-driven mechanisms.
