By studying the adjustment rules and ranges of access parameters,a distributed and adaptive access mechanism was proposed based on channel status information.By sensing and counting channel busy status,a node adjusting contention window linearly according to different access categories was designed,which separated the adjustment rules of parameters from the status of data transmissions and alleviated the effect of fixed ranges of contention window on performance.The simulation results demonstrate the validity and scalability of the proposed access mechanism.
