针对传统的带宽分配方法存在分配精度低、效率差等问题,提出无线激光通信网络的上行接入带宽动态分配方法。采用坐标延迟方法对相空间进行重构,引入统计信号处理法,获取上行接入带宽使用容量。采用上行轮询算法对无线激光通信网络上行接入带宽的周期空闲损失进行分析,采用固定周期的轮询机制,获取分配时隙,引入流量预测法,对无线激光通信网络上行接入带宽进行动态分配。实验结果分析,本文法的吞吐量及性能均要优于传统分配方法。
Aiming at the problems of low allocation accuracy and poor efficiency, the traditional bandwidth allocation method is proposed and the dynamic allocation of uplink access bandwidth in wireless laser communication network is proposed. The coordinate delay method is used to reconstruct the phase space, and the statistical signal processing method is introduced to obtain the uplink access bandwidth usage capacity. The uplink round robin algorithm is used to analyze the periodical idle loss of the uplink access bandwidth of the wireless laser communication network. The fixed period polling mechanism is adopted to obtain the allocated time slots. The traffic prediction method is introduced to dynamically update the uplink access bandwidth of the wireless laser communication network distribution. The experimental results show that the throughput and performance of the proposed method are better than the traditional method.
