摘要: 针对多接口多信道无线Mesh网络,提出了一种基于链路负载和链路“潜在的”干扰度的权值的分布式静态信道分配算法。给出基于链路负载和链路“潜在的”干扰度的权值的定义和基于权值的链表的构建方法;阐述了算法的设计思想和实现步骤。仿真实验测试结果表明,该算法不但能适应业务流量分布均匀或不均匀的状态,而且能相应地提高网络吞吐量,提升网络性能。

Abstract: A distributed static channel allocation algorithm based on the weight of link-load and link-“potential” interference degree is proposed for multi-interface multi-channel Wireless Mesh Network(WMN).This paper presents the definition based on the weight of link-load and link-“potential” interference degree,and the construction method of weight-based chain.Then it elaborates on design idea and implementation steps of the algorithm.The simulation results show that the algorithm not only can adapt to the states of uniform or non-uniform distributed traffic,but also can increase network throughput and improve network performance accordingly.
