Internet of things:是指通过各种信息传感器、射频识别技术、全球定位系统、红外感应器、激光扫描器等各种装置

物联网是一个通过各种信息传感设备和技术,实时采集各种需要的信息,实现物与物、物与人的泛在连接,从而实现对物品和过程的智能化感知、识别和管理的网络。它基于互联网,是互联网基础上的延伸和扩展,将各种信息传感设备与网络结合起来而形成的一个巨大网络。
在物联网应用中有三项关键,分别是感知层、网络传输层和应用层。感知层负责采集各种需要的信息,包括各种传感器、射频识别技术、全球定位系统、红外感应器、激光扫描器等;网络传输层负责将采集的信息通过网络进行传输,包括互联网、移动通信网、局域网等;应用层则是将感知层和网络传输层的数据进行处理和应用,以实现对物品和过程的智能化感知、识别和管理。
物联网的应用非常广泛,可以应用于智能交通、智能医疗、智能家居、智能物流、智能农业等领域。通过物联网技术,可以实现更高效、更精确的管理和监控,提高生产效率和生活品质。物联网的应用正逐渐改变着我们的生活方式和工作方式。例如,在智能家居领域,物联网可以实现家庭设备的互联互通,通过智能控制中心统一管理家庭的各种设备,包括照明、空调、门窗、安防等,提供更加舒适、便捷、安全的家居环境。在智能物流领域,物联网可以实现货物的实时跟踪和监控,提高物流效率和准确性,降低物流成本。在智能农业领域,物联网可以实现农田的智能化管理,实时监测土壤、气象等环境因素,提高农作物的产量和质量。
然而,物联网的发展也面临着一些挑战和问题。首先,安全和隐私保护是一个重要的问题。由于物联网设备数量庞大且分布广泛,如何保证数据的安全和隐私是一个巨大的挑战。其次,标准化和互操作性问题也是需要解决的问题。由于物联网涉及的设备和数据非常多,如何实现不同设备和系统的互操作性和数据交换是一个关键问题。最后,成本和能耗问题也是需要考虑的因素。由于物联网设备和系统的建设和维护成本较高,如何降低成本和能耗也是一个重要的研究方向。

Internet of Things for Architects: Architecting IoT solutions by implementing sensors, communication infrastructure, edge computing, analytics, and security Learn to Design, Implement and secure your IoT infrastructure The Internet of Things (IoT) is the fastest growing technology market. Industries are embracing IoT technologies to improve operational expenses, product life, and people’s well-being. An architectural guide is necessary if you want to traverse the spectrum of technologies needed to build a successful IoT system, whether that’s a single device or millions of devices. This book encompasses the entire spectrum of IoT solutions, from sensors to the cloud. We start by examining modern sensor systems and focus on their power and functionality. After that, we dive deep into communication theory, paying close attention to near-range PAN, including the new Bluetooth® 5.0 specification and mesh networks. Then, we explore IP-based communication in LAN and WAN, including 802.11ah, 5G LTE cellular, SigFox, and LoRaWAN. Next, we cover edge routing and gateways and their role in fog computing, as well as the messaging protocols of MQTT and CoAP. With the data now in internet form, you’ll get an understanding of cloud and fog architectures, including the OpenFog standards. We wrap up the analytics portion of the book with the application of statistical analysis, complex event processing, and deep learning models. Finally, we conclude by providing a holistic view of the IoT security stack and the anatomical details of IoT exploits while countering them with software defined perimeters and blockchains. What You Will Learn Understand the role and scope of architecting a successful IoT deployment, from sensors to the cloud Scan the landscape of IoT technologies that span everything from sensors to the cloud and everything in between See the trade-offs in choices of protocols and communications in IoT deployments Build a repertoire of skills and the vernacular necessary to work in the IoT space Broaden your skills in multiple engineering domains necessary for the IoT architect
