Recently, for achieving multimedia communication in wireless LANs, many organizations research QoS. IEEE 802.11 is a standard for wireless LANs, and its media access control (MAC) protocol is the distributed coordination function (DCF). However, DCF does not have QoS mechanism. In this paper, distributed media access control using scheduling algorithm that obtains fair throughput by weight is proposed in ad hoc network. Moreover, our proposed scheme decreases the collision compared with conventional methods. The computer simulation was carried out and the performances were evaluated. It was clarified that our proposed scheme was effective.
