摘要
为实现高效的数据融合,提出了一种多源频谱资源数据融合方法.该方法将多个监测节点的频谱可用资源评估信息进行融合,利用意见形成理论,对关心地域的频谱资源可用性进行评估,为频谱动态管理提供资源状态信息.通过对不同网络规模的仿真分析,结果表明:在意见形成理论的基础上,通过设定"骨干"节点,缩减了50%的融合时间;在网络节点不超过100个的情况下,通过30轮次的沟通即可完成频谱资源数据的融合.
For making data fusion efficiently, the method of multi-source data fu- sion of spectrum resources based on complex network of opinion formation theory is proposed. The method uses multiple monitoring node spectrum resource assessment information to integrate, evaluate the spectrum resource usability, and provide sta-tus messages for dynamic spectrum management of spectrum resources. According to the simulation of different node number of the network, it shows that the inte-gration time is reduced by 50 % on the basis of opinion of formation theory by set-ting the backbone nodes, and, it costs no more than 30 rounds of communication interaction in the case of no more than 100 network nodes to achieve data fusion of the multiple nodes in the core area.
