摘　　要：文章在考虑网络信道分配优化模型的约束条件时,由于缺少对资源分配公平性的约束,导致信道分配后利用率较低,优化效果有限,为此,文章提出基于改进麻雀搜索算法的无线Mesh网络信道分配优化。文章采用数学模型描述网络中的信道分配问题,构建信道分配模型,结合Mesh网络的结构与特性,设计约束条件,包括网络连通性约束、信道容量约束和资源分配公平性约束。文章通过引入新的搜索策略和局部优化机制优化麻雀搜索算法,实施模型求解得到最佳信道分配方案。实验结果表明,在文章所提研究方法的应用下,Mesh网络信道的利用率得到了很大提升。When considering the constraints of the network channel allocation optimization model in the article,due to the lack of constraints on resource allocation fairness,the utilization rate of channels after channel allocation is low,and the optimization effect is limited.Therefore,the article proposes a wireless mesh network channel allocation optimization based on the improved sparrow search algorithm.The article uses a mathematical model to describe the channel allocation problem in networks,constructs a channel allocation model,and combines the structure and characteristics of Mesh networks to design constraint conditions,including network connectivity constraints,channel capacity constraints,and resource allocation fairness constraints.The article optimizes the sparrow search algorithm by introducing new search strategies and local optimization mechanisms,and implements model solving to obtain the optimal channel allocation scheme.The experimental results show that under the application of research methods,the utilization rate of Mesh network channels has been greatly improved.
