基于复杂网络的手机基站网络研究

Research on Mobile Base Station Networks Based on Complex Networks

将北京智能交通系统中的手机数据抽象成复杂网络,结合网络图论思想,将网络的节点换作手机数据中的基站,网络的边则产生于有关联的基站之间,那么就建立起一个手机基站网络的模型.在统计了大量手机数据的基础上,研究北京地区基站网络的复杂网络特性.统计分析表明,北京地区的基站网络具有较小的平均路径长度和较高的聚类系数(典型的小世界特性),其节点的度分布具有无标度特性.基站网络的复杂网络特性研究为手机基站的布局和通信公司运营质量的提高,提供了新思路.

The mobile date from Intelligent Transportation system of Beijing are abstracted as complex networks. On the basis of graph theory idea, the base stations and the relations between them are considered as nodes and edges. Then the base station network is built up. The property of complex network based the base station network in Beijing are researched on a large number of the statistical data. The analysis on the data indicates that the base station network of Beijing has small average path length and large clustering coefficient, which means it has typical property of small-world. The degree distribution of nodes shows scale-free property. The research provides a new method about the base stations distribution and the quality of mobile service provider improvement.
