摘要: Video traffic has dominated the global mobile data and creates fundamental need for continuous enhancement fast evolution in networks so as to accommodate its unprecedented growth. Despite surging interests radio access (RANs), latest technologies on dense heterogeneous wireless are shifting bottleneck of core networks. However, managing stalls video streams remains challenging. In an evolving system, network needs (i) determine rate each streaming request, (ii) distribute request among multiple sources, (iii) route so-generated peer-to-peer flows. this paper, we exploit user context propose optimized routing scheme (termed smart routing) stall management networks, which adaptively schedules rates with respect strategically routes so-scheduled demands. The proposed simultaneously addresses above three aspects by formulating them a joint optimization problem solving formulated algorithm provable approximation guarantee. Computer simulations validate efficiency scheme.
