构建光通信系统的最优信道选择模型,提升光通信系统的数据传输速率,降低传输时延。首先光通信系统中发送端和接收端之间的感知时间和传输时间,以传输速率最大化为目标函数,构建最优信道选择模型,采用改进离散蝙蝠算法求解模型目标函数,获取最小适应度值对应的结果为当前最优解,输出最优信道选择结果。测试结果显示:该方法具有较好的应用效果,最优信道选择比率结果均在0.944以上,可极大程度地保证最优信道的选择效果;数据传输最大时延结果为1.08 s,满足应用标准;信道选择后光通信系统的传输速率均在10 Mbps左右,其中最大值达到10.57 Mbps。

The optimal channel selection model of the optical communication system is constructed to improve the data transmission rate of the optical communication system and reduce the Transmission delay.First,the sensing time and transmission time between the sender and receiver in the optical communication system,taking the maximum transmission rate as the objective function,build the optimal channel selection model,use the improved discrete bat algorithm to solve the model objective function,obtain the results corresponding to the minimum fitness value as the current optimal solution,and output the optimal channel selection results.The test results show that this method has good application performance,with the optimal channel selection ratio results above 0.944,which can greatly ensure the selection effect of the optimal channel;The maximum delay result of data transmission is 1.08 seconds,which meets the application standards;After selecting the channel,the transmission rate of the optical communication system is around 10 Mbps,with a maximum value of 10.57 Mbps.
