基于IHHO算法的室内可见光灯源布局优化

Optimization of Indoor Visible Light Source Layout based on IHHO Algorithm

针对室内可见光通信存在接收功率不平坦、光照度不均匀等问题,提出了一种改进哈里斯鹰优化算法(IHHO)对室内传统四灯源布局的灯源位置信息进行优化。经Matlab R2018b仿真表明,IHHO算法优化的灯源布局功率分布上更均匀,功率方差为0.359 dBm,照度范围为368.32~665.18 lx,照度均匀度为72.25%,均优于原始灯源布局、PSO算法以及HHO算法优化的灯源布局,所以IHHO算法的灯源布局优化方法对室内可见光通信有明显的改善效果。

An improved Harris Hawk Optimization Algorithm was proposed to optimize the position information of light sources in traditional indoor four light source layouts,addressing the issues of uneven reception power and uneven illumination in visible light communication.Simulation with Matlab R2018b showed that the optimized light source layout in this paper has a more uniform power distribution,with a power variance of 0.359 dBm,an illumination range of 368.32~665.18 lx,and an illumination uniformity of 72.25%,all of which were better than the original light source layout,PSO algorithm,and HHO algorithm optimized light source layout.Therefore,the proposed light source layout optimization method in this paper had a significant improvement effect on indoor visible light communication.
