针对无线紫外光散射通信中非视距(NLOS)传输特点和信道干扰模型，采用基于粒子群的无线紫外光网络快速信道分配方法，充分考虑了空间角度对信道冲突矩阵的影响，实现了一种定向、快速的信道分配新方法。仿真分析了该算法的平均迭代次数、平均干扰度以及收敛时间与粒子群数目和信道数目的关系。实验结果表明此紫外光网络信道分配方法具有收敛速度快、冲突度小的优势，保障了无线紫外光网络信道分配的快速性和准确性。

A fast channel allocation method in wireless ultraviolet network based on particle swarm is adopted aiming at the characteristic of non-line-of-sight and channel interference model. Fully considering the influence of conflict matrix caused by the space angle, a directional and fast channel allocation is designed. The relationship between average number of iterations, interference degree, convergence time and particle swarms number, channels are simulated and analyzed. Experimental results show that the channel allocation method of ultraviolet light network in this paper has the advantages of fast convergence speed and small degree of conflict. Meanwhile, it can ensure the quickness and accuracy of the channel allocation in wireless ultraviolet network.
