摘　　要：无线视频传感器网络具有视频信息量大、无线信道带宽有限和传输误码率较高等特点,TCP等常用的网络传输协议并不能很好地满足无线视频传感器网络对视频传输的需求。本文对一种适用于无线视频传感器网络的实时传输协议(RTP)进行了分析,阐述了基于RTP实现H.264视频传输的方法,并进行了相关的网络性能测试。结果表明,该方法在几乎不损失视频传输效率的基础上,降低了视频传输误码率,能满足视频无线网络传输的需要。A wireless video sensor network has the characteristics of large amount in video information,limited bandwidth in wireless channel and high transmission error rate,which makes its demand in real-time video transmission largely unsatisfied by traditional network transport protocols.This paper analyzes a real-time transmission protocol（RTP） for wireless video sensor networks and discusses a kind of H.264 video transmission method based on RTP.Testing results prove that the method can reduce the error rate on the network performance in video transmission,thus meeting the demand in wireless network video transmission.
