A relay-based multirate protocol in infrastructure wireless LANs
Jain‐Shing Liu, Yung‐Chang Wong · 2005
In this paper, we introduce a relay-based adaptive auto rate (RAAR) protocol that can find a suitable relay node for data transmission between transmitter and receiver. In RAAR, a MH can dynamically adjust its modulation scheme to achieve the maximal throughput according to the transmission distance and the channel condition. Evaluation results show that this scheme can provide significant improvements on throughput for nodes located at the fringe of the AP's transmission range, thus remarkably improving overall system performance.
