无线弱实时多媒体业务传输模型分析

Analysis of Transfer Architecture for Wireless Semi Real -time Multimedia Application

提出了无线“弱实时多媒体业务”的概念。利用RTP协议的体系框架,结合自适应的ARQ重传算法,实现了新的传输模型。仿真结果显示,该传输模型很好地解决了无线“弱实时多媒体业务”传输在时延、吞吐量抖动和差错概率之间的均衡问题。

We propose the concept of wireless se mi real -time multimedia for the new a pplication.Combined with the ARQ algorithm from TCP and the skeleton of RTP,we realiz e the new architecture of semi real -time multimedia transportation.From the emulation,it shows the good balance between trans-portation delay and error.
