Retransmission Rate Selection for Block-Based Partial Packet Recovery
Source: Florida State University
In a Wi-Fi network, partial packets often exist which are packets with some errors. Recent works show that much better efficiency can be achieved by repairing such packets instead of retransmitting such packets. In this paper, the authors propose a rate selection scheme for the repair packets, referred to as ReSel. ReSel is developed under the Maranello partial packet recovery framework and is motivated by two observations. The repair packet is sent shortly after the original packet and will likely experience similar channel conditions as the original packet. Therefore, given the recent failure on the original packet, a lower data rate should be used for the repair packet.
