Abstract: A MAC protocol, useful for wireless local area networks (WLANs), is provided for improving throughput efficiency. The protocol includes three concurrent processes, and the channel is divided into a contention subchannel and a transmission subchannel. In the contention process, all nodes use the standard RTS/CTS mechanism operated on the contention channel to contend for a right of transmission. When one node gains the right, all the nodes store the contention result into their respective contention queue (CQ) buffers. In the transmission process, the nodes sequentially transmit their data over the transmission channel according to the order of the nodes stored in the CQ buffers. When one node finishes data transmission, the CQ buffers are updated. The contention process and the transmission process are connected by the queuing process, where each node dynamically updates its own CQ buffer according to the contention result and each instance of data transmission.

Abstract translation: 提供了一种用于无线局域网（WLAN）的MAC协议，用于提高吞吐量效率。 该协议包括三个并发进程，并且该信道被划分为竞争子信道和传输子信道。 在竞争过程中，所有节点都使用在争用通道上运行的标准RTS / CTS机制来争取传输权。 当一个节点获得权限时，所有节点将争用结果存储到它们各自的争用队列（CQ）缓冲器中。 在传输过程中，节点根据存储在CQ缓冲器中的节点的顺序，依次通过传输信道发送它们的数据。 当一个节点完成数据传输时，更新CQ缓冲区。 竞争过程和传输过程通过排队过程连接，其中每个节点根据竞争结果和每个数据传输实例动态更新自己的CQ缓冲区。

Abstract: A MAC protocol, useful for WLANs, is provided for random access over a channel. The protocol includes three concurrent processes. The channel includes a contention subchannel and a transmission subchannel. In the contention process, all nodes use the standard RTS/CTS mechanism operated on the contention subchannel to contend for a transmission right. When one node gains the right, all the nodes store the contention result into their respective contention queue (CQ) buffers. In the transmission process, the nodes sequentially transmit their data over the transmission subchannel according to the order of the nodes stored in the CQ buffers. When one node finishes transmission, the CQ buffers are updated. The contention and transmission processes are connected by the queuing process for dynamically updating each node's CQ buffer. When OFDM is used in a random-access system, numbers of data subcarriers in both subchannels for maximizing the system throughput are given.
