1.1. Tổng quan về IoT ▪ What is the Internet of Things (IoT) ? ▪ IoT is the network of things, with clear element identifcation, embedded with software intelligence, sensors, and ubiquitous connectivity to the Internet ▪ (Book: Internet of Things From Hype to Reality) ▪ Components: • Sensors: to collect information. • Identifiers: to identify the source of data (e.g., sensors, devices). • Software: to analyze data. • Internet connectivity: to communicate and notify. ▪ “Things” = “anything”, “everything” ▪ Home appliances, building, car, people, animals, trees, plants, ... IoE = Internet of Everything (by Cisco) 6
Tổng quan về IoT ▪ How does IoT works ? ▪ IoT devices: smart devices (that use embedded systems such as processors, sensors and communication hardware) to collect, send and act on data they acquire from their environments. ▪ IoT devices share the sensor data they collect by connecting to an IoT gateway, which acts as a central hub where IoT devices can send data. ▪ Before the data is shared, it can also be sent to an edge device where that data is analyzed locally. Analyzing data locally reduces the volume of data sent to the cloud, which minimizes bandwidth consumption. 8
Tổng quan về IoT ▪ How does IoT works ? ▪ Sometimes, IoT devices communicate with other related devices and act on the information they get from one another. ▪ The devices do most of the work without human intervention, although people can interact with the devices -- for example, to set them up, give them instructions or access the data. ▪ The connectivity, networking and communication protocols used with these web-enabled devices largely depend on the specific IoT applications deployed. ▪ IoT can also use artificial intelligence and machine learning to aid in making data collection processes easier and more dynamic. 9
Tổng quan về IoT ▪ Why is IoT important ? ▪ IoT helps people live and work smarter. • For example: IoT-embedded devices -- such as cars, smartwatches or thermostats -- improve people lives. ▪ IoT is essential to business: • Real-time supervising of products/objects/system • Delivering insights into everything from the performance of machines to supply chain and logistics operations. ▪ IoT enables machines to complete tedious tasks without human intervention. • automate processes, reduce labor costs, cut down on waste and improve service delivery. • less expensive to manufacture and deliver goods, • transparency into customer transactions. 11
Tiến hóa của IoT ▪ The field of IoT has grown tremendously ▪ 1999: Kevin Ashton (Auto-ID Center, MIT) first mentioned the internet of things in a presentation about RFID (Source: IHS) 12
Tiến hóa của IoT ▪ IoT has evolved from the convergence of: ▪ Wireless technology ▪ Microelectromechanical systems ▪ Microservices ▪ Internet ▪ M2M (machine to machine) communication, evolved to next level ▪ 2010: broder consumer use (smart phones, smart TV) ▪ 2020: cellular IoT (2G/3G/4G/5G. LoRaWAN, LTE) ▪ 2023: billions of internet-connected devices ▪ Digital twins: virtual representation of a real-world entity or process 13

Internet of content (WWW, 1989, Tim Berners-Lee) https://en.wikipedia.org/wiki/History_of_the_World_Wide_Web 3. Internet of services (Web 2.0, Yahoo, Amazon, … ~2000, dotcom companies) 4. Internet of people (smart phones, social networks, iPhone1 2007) Internet of Things named 1999 https://iot-analytics.com/internet-of-things-definition/ 14
Tiến hóa của IoT 15 Idea: Move from Internet of People → Internet of Things • Internet xuất hiện ở khắp nơi trên thế ❖ Internet of Things kết nối mọi thứ giới (“things”) sử dụng các phương tiện • Ban đầu là để kết nối con người – con hạ tầng đã có. người

4th IR and IoT ▪ The Fourth Industrial Revolution and IoT ▪ 1st IR: transformed society with the introduction of machines and mechanized production. ▪ 2nd IR: introduced electricity, which led to mass production. ▪ 3rd IR: has been called the dawn of the information age. ▪ 4th IR: as "the fusion of technologies that is blurring the lines between the physical, digital, and biological spheres.“ (by Klaus Schwab) ▪ IoT is being called a major driver of the Fourth Industrial Revolution.
