摘　　要：为提高无线环境下的数据传输性能,对无线运用环境进行了研究,结合嵌入式系统的特征,提出了一种简单、可靠而实用的传输协议。它保留了UDP协议的全部功能及高效的特点,利用可靠报文处理流程及选择重传机制,实现数据实时可靠的传输。实验结果表明,该协议在无线网络中数据传送可靠性高,保持了良好的带宽利用率,为上层应用提供高效、可靠的数据传输服务。To increase the transmission ability in wireless environment, the special character of wireless environment application is studied. A simple, reliable and practical transmission protocol is proposed based on embedded system traits, which reserves all functions andhigh-efficiencycharacterofUDP. Real-time and reliable transmission with reliable process flow, batch retransmit mechanism is realized. Experiments showed that the proposed protocol achieve a high-reliable transmission ability, keep a nicer bandwidth utilization, and afford efficiency and reliable service for upper layer.
