基于节点度约束的无线通信网拓扑模型

摘要

To solve the topological model generating problem of wireless communication network, the existing methods for to-pological construction are analyzed. A topological evolving model of wireless communication network with the node degree constraint is proposed according to the characteristic of wireless communication network. The evolving method and the flow of algorithm on the wireless communication network are studied, and the degree distribution of the model is analyzed and calcu-lated. The degree distribution and network efficiency of the network are simulated. The simulation results indicate that the network generated by the model has the small-world characteristics and power-law distribution approximately, which can well satisfy the topological structure of wireless communication network.%为了解决无线通信网拓扑模型生成问题,分析了现有网络拓扑模型的不足,结合无线通信网的特点,提出了一种基于最大度约束的无线通信网拓扑演化模型.研究了网络拓扑模型的演化方式和算法步骤,解析计算了模型的度分布.对网络的度分布和网络效率等网络特性进行了仿真分析,仿真结果表明:模型生成的网络具有小世界特性和近似幂律分布,能够充分体现无线通信网的拓扑结构特性.
