| 摘 要： | 移动Ad hoc网络中为有效利用无线信道资源,提出一种多信道预约媒质接入(MRMA, Multichannel Reservation Multiple Access)协议.该协议在公共信道上发送Request-to-Send/Clear-to-Send(RTS/CTS)分组预约信道,采用基于ID的信道选择方案选择无冲突的业务信道传输数据分组,目的节点成功接收完数据分组后在另一个公共信道上回复Acknowledgment(ACK)分组,有效避免了暴露终端问题,使得相邻通信节点对可以同时使用相同的业务信道传输数据分组,空分复用大大提高了无线资源的利用率.采用多信道分别进行不同通信对的业务分组传输解决了在单信道上传输所带来的隐藏终端问题.仿真结果表明,在总信道利用率和平均分组延迟性能上,MRMA协议明显优于IEEE 802.11 RTS/CTS协议.

| Abstract: | A novel multichannel reservation multiple access(MRMA) protocol was presented for efficient channel sharing in mobile ad hoc networks.It employed request-to-send(RTS) and clear-to-send(CTS) dialogue on a common channel and flexibly selected conflict-free traffic channel to accomplish the transmission of data packet based on a novel channel selection scheme.The acknowledgment(ACK) packet for the data packet transmission was replied to the sender over another common channel,which effectively eliminated the in... |
