概要	In this paper, we proposed a MAC protocol for QoS realtime application in one-hop ad hoc wireless networks. The proposed protocol uses a random number at the beginning of sessions to avoid collisions, as other MAC protocols do. However, to increase the probability of successful transmission after an unsuccessful attempt to transmit a packet, only the nodes that transmitted the packet try to send a packet again. Furthermore, after successful transmission, the node that has been waiting longest has priority over the other nodes and can send a packet without risk of collision. The simulation results showed that highest priority nodes use as much bandwidth as necessary; lower priority nodes use as much as possible.
