【摘要】 无线传感器网络是一种新型的数据感知技术,由于网络由大量资源有限的传感器节点组成,并且容易受到环境干扰等因素的影响,数据在网络中传输时可能产生拥塞,造成数据传输不可靠,因此在无线传感器网络中设计合适的拥塞控制协议,进行可靠数据传输是很有必要的。分析了国内外已有的拥塞控制协议,指出了设计拥塞控制协议的一些考虑因素。更多还原

【Abstract】 Wireless sensor networks are novel data-acquiring technologies.The networks are composed of many resource-limited sensor nodes and prone to be interfered by the environment and other factors.It’s possible lead to congestion and unreliable data transferring when there is much data transferring in the networks.So it’s necessary to design appropriate congestion control and reliable data transfer protocols in wireless sensor networks.The congestion control problems in wireless sensor networks are provided and some congestion control protocols given in other literatures are analysed,at last some considerations of designing congestion control are given.更多还原
