无线传感器网络可靠数据传输协议的研究

Reliable Transport Protocols in Wireless Sensor Networks

数据的可靠传输是一个成熟的网络应该给用户所提供的基本服务。在能量受限和带宽受限的无线传感器网络（wireless sensor networks）中，同样需要可靠的数据传输。首先分析了TCP应用于无线传感器网络的不足，然后介绍了目前可靠数据传输协议的主要研究进展和关键技术，重点阐述了PSFQ、ESRT和RMST协议的应用场景和基本原理，分析了不同协议各自的优缺点，最后展望了可靠数据传输的研究方向和发展前景。

The reliable data transport should be provided as a kind of basic services in a well-developed network. In energy-limited and bandwidth-limited wireless sensor networks（WSN）, the reliable data transport is also indispensable. The paper first analyzes why TCP can＇t perform well in wireless sensor networks, and then presents current research progress and key technologies in reliable transport protocols in WSN, including several representative protocols such as PSFQ,ESRT and RMST. Application scenarios and fundamentals in these protocols are illustrated. At last, we summarize the research trend and prospect of reliable data transport in WSN.
