摘要
物联网中的无线传感网络有两个基本问题:网络节点的均匀覆盖和节点能量的消耗。对此,本文提出一种基于城市照明的区域性感知模型,将无线传输节点嵌入在公共照明系统中,形成了一个均匀覆盖整个区域、没有能量异构问题的无线传输网络,通过射频识别(RFID),感知区域中的人和物的类别、意图、位置等,同时提供人和物从区域中获得所需要的信息服务。并将该模型在某国际科技园中实现,建立了一个初级的物联网"感知区域"。
There are two main issues should be concerned in the wireless sensor network of the Internet of things：equal distribution and energy consumption of the net nodes.Thus,a model of the Internet of things in a sensing region based on urban lighting is introduced in this paper.In this model,wireless transit nodes are integrated in the public lighting system to build a wireless transit network covering the whole area perfectly without any energy heterogeneous problems.People and objects in the sensing region can be identified and localized by RFID,and their intentions can be perceived as well.The model has already been put into service in an international science park and a primary sensing region of the Internet of things has been built.
