Abstract

Abstract

In this paper, a proxy-based mobile streaming media system in WCDMA network is introduced. Two metrics, mean network transferring cost and mean playback startup latency of mobile terminals, to evaluate performance of a cache allocation algorithm in proxy are presented. Expressions for corresponding saving and integrated saving of the metrics under Mobile Batcing (MBatching) stream transmission scheme are developed. A cache allocation algorithm that applies to the mobile streaming media system is put forward to make the total integrated saving of all the streaming media program maximal. Simulation results demonstrate that the algorithm can make the total integrated saving larger, save more network transferring cost and achieve higher byte-hit rate than another allocation algorithm.
