无线激光通信网络的上行接入带宽动态分配

Dynamic Allocation of Uplink Access Bandwidth in Wireless Laser Communication Network

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。

Traditional bandwidth allocation methods has low precision and poor efficiency. Therefore,a dynamic method for uplink access bandwidth of wireless laser communication network is proposed. Delay coordinate method is used to reconstruct phase space,statistical signal processing method is used for obtaining its usage capacity,uplink polling algorithm is used for analyzing the periodic spare loss of the uplink access bandwidth in wireless laser communication network. Fixed periodic polling mechanism is used for obtaining allocation slot time and using the traffic prediction method to dynamicly allocate the uplink access bandwidth of wireless laser communication network. The experimental analysis results show that the throughput and performance of the proposed method are better than those of the traditional methods.
