Mobility-Aware Streaming Rate Recommendation System

In mobile multimedia streaming services, important requirements consist of the support of service continuity, the guarantee of acceptable Quality of Service (QoS) and insurance of steady Quality of Experience (QoE). How to get a uniform data exchange rate during the entire (or partial) course of a streaming service while a user is on the move is an important challenge. Generally speaking, the streaming rate of a multimedia service may heavily fluctuate due to the unavailability or deficiency of resources along the movement path of a user. To cope with this challenge, this paper proposes a framework that integrates user mobility prediction models with resource availability prediction models to keep a constant or less fluctuating streaming rate and to ultimately ensure steady QoE. Simulations are conducted to evaluate the performance of the proposed framework in achieving its design objectives and encouraging results are obtained.
