雾计算网络的成本效率分析

Cost efficiency analysis of fog computing network

雾计算是一种减少时延和网络拥塞的先进技术,可为物联网(IoT)网络提供经济效益。每个云数据中心可分配不同数量的计算资源,从不同的雾节点到不同的用户,这样计算资源可被用户有效地利用。目前对于雾计算网络中的计算资源分配问题,可将服务质量和成本都作为资源分配的重要指标。文章针对三层雾计算网络,首先定义了雾计算网络的成本效率,其次分别讨论分析了云数据中心、雾节点和用户的成本效率。

Fog computing is an advanced technology that reduces latency and network congestion,and can provide economic benefits for Internet of Things(IoT)networks.Each cloud data center can allocate different amounts of computing resources,from different fog nodes to different users,so that computing resources can be effectively utilized by users.At present,for the problem of computing resource allocation in fog computing networks,service quality and cost can be regarded as important indicators of resource allocation.For this three-layer fog computing network,the cost efficiency of the fog computing network is defined,and then the cost efficiency of cloud data center,fog node,and user are analyzed respectively.
