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。
Proposed wireless “weak real-time multimedia business” concept. With the framework of RTP protocol and the adaptive ARQ retransmission algorithm, a new transmission model is realized. The simulation results show that the proposed transmission model solves the problem of the balance between delay, throughput jitter and error probability in wireless “weak real-time multimedia services” transmission.
