| 摘 要： | 提出一种MAC层竞争信道的FRA算法。FRA算法以实验测得的数据帧长和信道速率作为调节CWmin的因子，提高了发送大数据帧或高速信道节点的信道占用时间。实验结果表明，该算法在速率、帧长各异的无线网络环境中，网络总吞吐率比DCF协议提高约70%。

| Abstract: | A MAC algorithm Frame-cum-Rate Adjustment（FRA） is proposed to contend for the wireless channel. In FRA, the value of CWmin is adjusted based on frame size acquired by lots of experiments and transmission rate. The wireless station with large frame size and high transmission rate can obtain high probability to access wireless channel. Simulation results show that compared with DCF, FRA increases the network throughput by 70% when different frame sizes and transmission rates coexist. |
