IEEE 802.11 DCF is the MAC protocol currently used in wireless LANs. However, due to idle and collision times, 802.11 DCF performs poorly when it comes to channel utilization, system throughput, and channel access time. To overcome these sources of inefficiency in 802.11 DCF, the authors propose a distributed and dynamically adaptive MAC protocol for wireless networks, called Token-DCF with append process and change contention window size. Main focus of their approach is on reducing idle and collision times by introducing an algorithm of token passing using append process and change contention window size.
