【摘要】As the rapid development of wireless sensor network (WSN), the demands of limited radio frequency spectrum rose sharply,thereby dealing with the frequency assigmnent of WSN scientifically and efficiently was a hard nut to crack.To improve the frequency utilization rate and solve the dynamic frequency configuration problem of multi-nodes in WSN,a novel spectrum management system for WSN combined with cloud computing technology was proposed in this paper. The frequency assignment system was based on the network architecture of WSN.The system also took advantage of cloud resource allocation, distributed memory and self-adaptive analysis so that it allotted the frequency dynamically and automatically in WSN.This was an efficient path to meet the needs of WSN spectrum management.%随着无线传感器网络的快速发展,频谱需求急速增长,频谱资源日渐紧缺,无线传感器网络频率的高效分配已成为一个亟需解决的难题.为了提高频谱的利用效率和应对无线传感网络中多节点频率信息动态配置问题,提出了一种基于云计算的WSN动态频率分配系统.该动态频率分配系统在无线传感器网络的无线通信框架上,利用云资源调度、分布式数据管理、自适应分析决策支持等技术,实现对无线传感器网络中频率资源的动态分配.
