【电信学】【2016】具有多种直接通信方式的物联网

本文为美国密苏里大学（作者：KAUSTUBHDHONDGE）的博士论文，共152页。

物联网（IoT）是嵌入有电子、软件、传感器和网络连接的物理对象或事物构成的网络，使得这些对象能够收集并交换数据。物联网的快速发展正在推动家庭、工作场所和工业中日常使用的设备智能化。物联网设备通常通过射频（RF）进行通信，例如WiFi和蓝牙。

本文深入分析了不同无线通信方法在距离、能量效率、辐射模式等方面的不同特点。我们发现，采用良好的通信方法可能不是最有效的，并且可能存在具有特定应用程序所需属性的其它替代通信方法。我们设计构建的IoT应用，利用了完全替代、创新和互补的无线通信方法，包括射频、红外（IR）和可见光。我们已经开发了各种物联网应用，这些应用提供安全和认证，使车辆能够与智能手机或其它智能设备通信，为智能设备提供节能式准确定位，并使工业物联网(IIoT)中的节能通信成为可能。

Internet of Things (IoT) is a network ofphysical objects or things that are embedded with electronics, software,sensors, and network connectivity - which enable the object to collect andexchange data. Rapid proliferation of IoT is driving the intelligence in thingsused daily in homes, workplaces and industry. The IoT devices typicallycommunicate via radio frequency (RF), such as WiFi and Bluetooth. In thisdissertation we deeply analyze the various characteristics of differentwireless communication methods in terms of range, energy-efficiency, andradiation pattern. We find that a well-established communication method mightnot be the most efficient, and other alternate communication methods with thedesired properties for a particular application could exist. We exploitradically alternative, innovative, and complimentary wireless communicationmethods, including radio frequency, infrared (IR), and visible lights, throughthe IoT applications we have designed and built with those. We have developedvarious IoT applications which provide security and authentication, enablevehicular communications with smartphones or other smart devices, provideenergy-efficient and accurate positioning to smart devices, and enableenergy-efficient communications in Industrial Internet of Things (IIoT).
