Under timevarying wireless channels, a device needs to tune its transmission rate dynamically for more efficient utilization of the physical link. ...
In this paper, we propose a practical rate adaptation algorithm, Smart Sender, which utilizes both statistics and the received signal strength indicator (RSSI) of ACK packets to determine the transmission ...
By probing at a promising rate, the sender can tune to the optimal rate as soon as possible. 1) Long-term statistics for system stability: Previous ARFlike schemes only use heuristics with consecutive ...

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. ...

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. ...
