Abstract :
In this paper a Media Aware Radio Link Adaptation (MARLA) scheme for H.264/AVC video transmission is proposed to improve the video delivery quality over HSDPA networks. First of all, by taking both the packet importance and urgency into consideration, we design a transmission utility function to measure the packet priority. Secondly, an optimization model for radio link adaptation is built to maximize the video transmission utility for each mobile station. Finally, through analysis on the characteristics of the radio link adaptation mechanism in HSDPA, we obtain a low complexity optimal solution to the optimization model. Simulation results show that our proposed scheme can achieve higher video quality than the existing algorithms.
