Deadline Probing: Towards Timely Cognitive Wireless Network [chapter]

Panlong Yang, Guihai Chen, Qihui Wu
2008 Lecture Notes in Computer Science  
As they focus more on transmitting packets with the optimal channel, resources are not efficiently used when sufficient channels are available in multi-radio multi-channel systems.  ...  In this paper, we propose a transmission deadline probing paradigm, and an optimal probing and transmission schedule with time constraints is proposed, which is a pure threshold policy.  ...  In all those applications, optimal channel probing can be achieved in order to set a tradeoff between obtaining useful channel information and consuming valuable probing times.  ...

WSN05-3: Practical Rate Adaptation for IEEE 802.11 WLANs

Qiuyan Xia, Mounir Hamdi, Tsz Ho Chan
2006 IEEE Global Communications Conference, Exhibition, & Industry Forum (GLOBECOM)  
However, because of the time-varying characteristics of a wireless channel, no single rate can be optimal under all scenarios, and the device needs to tune its transmission rate dynamically.  ...  In this paper, we propose a Practical Rate Adaptation algorithm, which utilizes both statistics and RSSI of ACK to decide the transmission rate that maximizes the throughput.  ...  The novelty of our rate adaptation scheme lies in its great adaptability to a variety of channel conditions robust enough to be easily adopted for current wireless hardware.  ...
