NUM-Based Fair Rate-Delay Balancing for Layered Video Multicasting over Adaptive Satellite Networks

摘要: Trading delay and rate in upcoming satellite networks are of paramount interest. In this paper, we present a solution to optimally distribute resources across MAC, IP APP layers deal with the problem efficiently reliably delivering low latency high inelastic services over such networks. order do so, formulate rate/delay balancing according Network Utility Maximization (NUM) paradigm assuming Scalable Video Coding (SVC) feeding cross-layer DiffServ architecture, an adaptive physical layer. We solve not only bit loading queues but also video distribution be sent among layers, all constrained by requirements. The solution, which provides fair rate-delay trade-off, happens on water filling load queuing it is suitable for multicasting scenarios. Finally, propose full protocol design, implementation, performance evaluation based truly available standardized tools, hence, ready-to-use. Our significantly outperforms non approaches terms quality, dynamically adapts channel traffic variations.
