摘　　要：由于当前已有方法未能对用户需求进行分析,导致可见光通信异构网络系统吞吐量以及平均满意度下降。为此,提出一种可见光通信异构网络频谱资源分配算法。将可见光通信异构网络系统最大容量作为目标,综合考虑用户需求以及最大功率限制等约束,构建可见光通信异构网络频谱资源分配模型。将模型中的对偶问题分解为简单的子问题,通过定向变异的遗传算法进行信道分配,采用拍卖算法进行信道内功率分配,最终实现网络频谱资源分配。实验结果表明,所提算法可以有效提升可见光通信异构网络系统吞吐量以及平均满意度。Due to the failure of existing methods to analyze user needs,the throughput and average satisfaction of visible light communication heterogeneous network systems are reduced.Therefore,a spectrum resource allocation algorithm for visible light communication heterogeneous networks is proposed.Taking the maximum capacity of visible light communication heterogeneous network system as the goal and comprehensively considering the constraints such as user demand and maximum power limit,a spectrum resource allocation model of visible light communication heterogeneous network is constructed.The dual problem in the model is decomposed into simple subproblems.The channel allocation is carried out by directional mutation genetic algorithm,and the power allocation in the channel is carried out by auction algorithm.Finally,the network spectrum resource allocation is realized.Experimental results show that the proposed algorithm can effectively improve the throughput and average satisfaction of visible light communication heterogeneous network systems.
