| 摘 要： | 提出一种两跳的协作传输方案,该方案利用无线信道广播特性,并结合应用层视频包的信息,通过选择成功监听到数据包的节点来承担协作传输任务,以此来降低重传次数,降低包的接入和服务延时,提高传输效率,以解决在无线环境下流媒体传输存在丢包率高、吞吐量受误码率影响、端到端的传输延时等QoS问题.

| Abstract: | In this paper,a two-hop cooperative transmission program is proposed,which exploits the broadcast feature of wireless channels,and is combined with the video package of the application layer,and passes the retransmission or forwarding responsibility to a neighboring node that has successfully snooped the data transmission.The proposed method thereby reduces the retransfer times,packet access time and services delays,improves transmission efficiency and solves the packet loss rate,throughput,error rate end t... |
