Abstract:

A scheduling algorithm based on the two dimensional utility function is proposed to guarantee the packet drop ratio and play-out outage ratio of streaming application in the mixed service scenario. The simulation results show that guarantee capability for the drop and play-out outage ratio of the proposed scheme outperforms the modified-largest weighted delay first algorithm and exponent proportional fair algorithm, which only take the head-of-line delay into consideration.

Key words: high speed downlink packet access;quality of service, scheduling, the utility function
