基于物联网的资源映射算法研究

在物联网环境下,大量物品通过各种传感技术加入到网络中。如何有效地组织和管理日益增加的物理资源,如何满足多样化的物联网应用需求,将成为物联网发展中一个非常重要的问题。网络虚拟化技术通过有效地管理虚拟用户请求到物理资源的映射来达到充分共享物理资源的目的,在解决该物联网问题时体现出它的优势。在现有互联网虚拟网络映射算法的基础上,针对物联网环境中物理节点所呈现的异构性特点,提出了一种基于物联网的虚拟网络到物理网络的资源映射算法。

Research on Resources Mapping Algorithm Based on the Internet of Things

In the environment of the Interner of Things,large number of objects are connected into the Internet.How to organize and manage the increasing substrate tesources and how to satisfy various application requiremenrs of the Interner of Things will become an essential question.Network virtualization assigns the substrate resources to the virtual user requests efficiently in order to share the substrate resources,and it shows its advantage in solving the question above.So,referring to the existing virtual mapping algorthm in the Interner and the heterogeneous character the substrate resources in the Internet of Things present,we propose a resources mapping algorithm from virtual network to substrate network based on the Intetnet Intemet of Things.
