• Performance Analysis of CSMA protocols
  • Notations:

    Time unit = length of a slot G = the offered load (number of attempted transmissions per time unit) S = the throughput (number of successful transmissions per time unit)

  • Performance of the various CSMA protocols:

    Notations:

    S1 = the throughput of the 1-persistent CSMA protocol Sn = the throughput of the non-persistent CSMA protocol Sp = the throughput of the p-persistent CSMA protocol
