In this paper, a novel cross-layer optimization scheme for video streaming in wireless relay networks is proposed. It takes into account of delay constraints at the application (APP) layer, relay node selection at the MAC layer and dynamic fading of wireless channels at the physical (PHY) layer in an integrated mode to improve the quality of video transmission. At the PHY layer, a finite state Markov...
With the rapid increase of mobile devices, wireless networks face spectrum exhaustion and insufficient bandwidth utilization problems. Cooperative communication is a promising approach to improve throughput in wireless relay networks. Recent researches mainly focus on cooperative communication methods in PHY or MAC layers separately to improve data transmission performance. Considering a typical video...
