无线数据可靠传输协议研究及应用
摘要
随着无线通信技术的快速发展,无线网路逐渐成为信息数据接入的关键媒介。移动无线通信网络因为自身的一些缺陷,使得如何让数据在该媒介上进行可靠高效的传输,成为人们关注和研究的热点问题。
本文首先对目前广泛使用的TCP(传输控制协议)和UDP(用户数据报协议)进行了详细的分析,针对标准TCP在有线网络上取得的巨大成功却不能很好适应无线移动通信网络的问题,在分析总结目前的学者专家研究成果的基础上,给出了基于显式拥塞控制的多级反馈的TCP拥塞控制机制MLF_TCP,仿真结果表明,该机制可以明显地提高吞吐量,降低丢包率,减少拥塞次数。
其次,分析研究了可靠数据报传输协议RUDP,并在cdma无线网络下将其与TCP、UDP进行了比较,结果表明RUDP具有比TCP更高的数据传输效率,比UDP具有更高的可靠性,在移动网络中的某些应用中,RUDP具有较好的实用性。
最后,根据上述实验结果并根据实际需要,将RUDP协议应用在了车辆视频监控系统项目中,实现了预定的系统功能,并较好地满足了数据传输的高效性、可靠性的需求。因此分析和研究移动通信网络中的数据可靠高效传输协议具有非常好的理论研究价值及广阔的市场应用前景。
With the rapid development of wireless communication technology, wireless data access has become a key information medium. Mobile wireless communication network because some of its shortcomings, so how to get data on the media, reliable and efficient transmission, known as the people's attention and research hot spots.
Firstly, the current widespread use of TCP (Transmission Control Protocol) and UDP (User Datagram Protocol) for a detailed analysis, for the standard TCP in the wired network to achieve great success and it can not well adapt to the problem of wireless mobile communication network in the analysis of present day scholars based on the results presented based on Explicit Congestion Control is a multi-polar feedback TCP congestion control mechanism MLF_TCP, simulation results show that the mechanism can significantly improve throughput and reduce packet loss rate, to reduce congestion times.
Secondly, the analysis of a reliable datagram protocol RUDP, and cdma wireless network it with TCP, UDP were compared, results showed that the RUDP has a higher data transmission than TCP efficiency, more reliable than UDP, In mobile networks in some applications, RUDP with good practice.
Finally, according to the experimental results and the actual need, to RUDP protocol used in the vehicle video surveillance system project, to achieve the intended system functions, and better meet the data transmission efficiency, reliability. Therefore, analysis and study of mobile communication networks in a reliable and efficient data transmission protocol has a very good theory of value and a broad market prospect.
