2005 IEEE 这是一个典型的Ad hoc场景.紧急情况下的临时自组网络.虽然之前的论文中把它标记为out-of-band global coverage,但这个也是分组的,每个组有个gateway. 核心采用了Spectrum  Pooling,Distributed Spectrum Assignment. “Spectrum pooling serves as a physical layer signallingfor detection of primary users, whil…

2009 Elsevier 综述了认知无线AD Hoc网络中的各个方面的研究进展及面临的挑战.包括传输层.网络层.链路层的协议设计. 根据CCC(common control channel)的实现思路不同,其把MAC层的不同实现分成了两部分,并分别给出了实现的例子.现在就列出如下,供以后参阅. 1.  in-band ccc 意思是说,ccc的实现不需要独立的一个信道,而是和数据传输公用同样的信道.这种ccc是临时的,而且是节点相关的,一对节点对应自己的ccc(其实就是自己的数据传输信道).好…

好吧,这是09年七月发布在IEEE Communications Magazine的一篇文章. 核心二个词:overlay cognitive radio network,tcp 讲的是,在认知无线网中TCP协议性能受影响的问题:为什么受影响,受到怎么样的影响,到什么程度.然后用NS2模拟,给出了一些结论. 总归的一些结论是:tcp在dsa网路中性能受影响的因素比传统网络多了一个,叫service interupption.其实就是由于Primer User的介入而导致的Second User的…

2010 这个呢,就是time slotted的DSA网络MAC层协议. 跟上一篇单纯的Multi Channel实现类似,不过这里是CR网络,因为多了嗅探等操作. 简单的说,time slotted的协议,是要求全局同步操作的,而之前提过的random access不需要.同步操作是由定期的beacon发送来实现的,即IEEE 802.11的TSF,通过定期的beacon把时间分成两部分:ATIM窗口部分和数据传输部分.在本论文里,在ATIM窗口部分,完成了同步的功能.嗅探的功能.嗅探结果共享…

This full text paper was peer reviewed at the direction of IEEE Communications Society subject matter experts for publication in the WCNC 2008 proceedings 这是个很dt的一个协议设计.不知道为什么会这么设计. 正如前前一篇文章中提到的.这篇论文设计的Mac协议是out-of-band local coverage的.out-of-band 依然…
