  1. AFR partial MAC proposal for IEEE 802.11n Qiang NiNational University of Ireland, Maynooth e-Mail: qiang.ni@ieee.org Tian-ji Li, Thierry Turletti INRIA Sophia Antipolis Yang XiaoUniversity of Memphis, USA Qiang Ni, et al

  2. Outline • Ideal throughput analysis for 802.11n • Actual effective throughput analysis under noisy environments • Our packet Aggregation with Fragment-Retransmission (AFR) proposal • Simulation analysis Qiang Ni, et al

  3. Ideal throughput analysis for 802.11n (1) 802.11 MAC: DCF (Distributed Coordination Function) Ideal throughput: Throughput Upper Limit (TUL): Qiang Ni, et al

  4. Ideal throughput analysis for 802.11n (2) Payload size = 1024bytes Your throughput never higher than 50Mbps with 1Kbyte frame!! Qiang Ni, et al

  5. Ideal throughput analysis for 802.11n (2) MAC and PHY parameters for 802.11 a/b/n Qiang Ni, et al

  6. Ideal throughput analysis for 802.11n (3) Maximum throughput while only one parameter is modified Qiang Ni, et al

  7. Ideal throughput analysis for 802.11n (4) Maximum throughput while multiple parameters are modified Qiang Ni, et al

  8. Ideal throughput analysis for 802.11n (5) Maximum throughput of 802.11e EDCA burst-ACK scheme Qiang Ni, et al

  9. Ideal throughput analysis for 802.11n (5) Maximum throughput of a simple packet aggregation Qiang Ni, et al

  10. Actual effective throughput under noisy environments (1) • Things are different when we consider noisy channels (errors) Gaussian channel: pe , packet error rate (PER), Pb , bit error rate (BER) • Actual effective throughput ( ) Qiang Ni, et al

  11. Actual effective throughput under noisy environments (2) PHY layer peack rate = 216Mbps Is simple packet aggregation acceptable?? Qiang Ni, et al

  12. Our solutions: Aggregation with Fragment-Retransmission (AFR) Qiang Ni, et al

  13. AFR (1) MAC data frame for the AFR scheme MAC ACK frame for the AFR scheme Qiang Ni, et al

  14. AFR (2) One example of the AFR protocol Qiang Ni, et al

  15. Simulation analysis Qiang Ni, et al
