Opportunistic Media Access for Multirate Ad Hoc Networks

  title={Opportunistic Media Access for Multirate Ad Hoc Networks},
  author={. Sadeghi and Vikram Kanodia and Ashutosh Sabharwal and Edward Knightly},
The IEEE 802.11 wireless media access standard supports multiple data rates at the physical layer. Moreover, various auto rate adaptation mechanisms at the medium access layer have been proposed to utilize this multi-rate capability by automatically adapting the transmission rate to best match the channel conditions. In this paper, we introduce the Opportunistic Auto Rate (OAR) protocol to better exploit durations of high-quality channels conditions. The key mechanism of the OAR protocol is to… CONTINUE READING
