摘　　要：在每个终端仅配置一套无线信号收发装置且信道速率较低(1 Kb/s^10 Kb/s)的情况下,信道需要划分成多个不重叠的子信道组建Ad Hoc网络。针对上述要求,提出一种改进的基于多信道的MACA-BI协议——RIMA-MC。该协议通过减少控制开销、增加信道空间复用度等方法提高低速Ad Hoc网络的吞吐量。在低速、高业务量网络中分析该协议的吞吐量,通过与MACA-BI及基于RTS/CTS的协议比较,证明RIMA-MC具有更好的表现。A new Medium Access Control（MAC） protocol for Ad Hoc networks named RIMA-MC（Receiver Initiated Multiple Access based on Multiple Channels） is introduced. The protocol which extends the usage mode of MACA-BI to multi-channel condition is designed to be applied in circumstances that the channel has low speed（1 Kb/s-10 Kb/s）, whereas can be divided into multiple sub-channels, and every terminal is equipped with only one transmitter. RIMA-MC intends to increase the throughput by means of reducing the control overhead and increasing the spatial reuse of the channel. The throughput performance of the protocol versus MACA-BI and RTS/CTS-based protocol is analyzed, which proves that RIMA-MC archives higher throughput in high loads.
