MPEG has recently proposed Server and Network Assisted Dynamic Adaptive\nStreaming over HTTP (SAND-DASH) for video streaming over the Internet. In\ncontrast to the purely client-based video streaming in which each client makes\nits own decision to adjust its bitrate, SAND-DASH enables a group of\nsimultaneous clients to select their bitrates in a coordinated fashion in order\nto improve resource utilization and quality of experience. In this paper, we\nstudy the performance of such an adaptation strategy compared to the\ntraditional approach with large number of clients having mobile Internet\naccess. We propose a multi-servers multi-coordinators (MSs-MCs) framework to\nmodel groups of remote clients accessing video content replicated to spatially\ndistributed edge servers. We then formulate an optimization problem to maximize\njointly the QoE of individual clients, proportional fairness in allocating the\nlimited resources of base stations as well as balancing the utilized resources\namong multiple serves. We then present an efficient heuristic-based solution to\nthe problem and perform simulations in order to explore parameter space of the\nscheme as well as to compare the performance to purely client-based DASH.\n
