Reducing Idle Time and Collision Time in Token DCF Using Swap and Append Process for Wireless Network
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 swap or append process. Main focus of their approach is on reducing idle and collision times by introducing an algorithm of token passing using swap or appends process.
