In this paper, the authors use medium access protocol with the use of proactive messages. The 802.11 ec: collision avoidance with contention algorithms provides a better efficiency, robustness, improves throughput and reduce hidden terminal collision. The most popular protocols use contention based algorithms to ensure proper channel utilization and sharing. The problem with control message based techniques is the high time requirement for managing the control messages. A possible enhancement is to use a turn based approach similar to time division multiplexing allocation, which provides different time-slots to different data-streams (in the time division multiplexing case to different transmitters) in a cyclically repetitive frame structure.
