Adaptive Backoff Algorithm for Contention Window for Dense IEEE 802.11 WLANs
Algorithm 2
Adaptive backoff algorithm of contention window.
while (contention) | A station observes the channel for backoff period. | Calculate using (5). | Estimate , following the procedure in Algorithm 1. | Calculate using (10). | Choose a random backoff value from the range [0, ]. | Decrement backoff timer by one when the channel is idle as DCF protocol. | Transmit a packet when the backoff timer expires. | End |
