The Internet of Things (IoT) is a popular buzzword right now, but unlike many fads that have come and gone, the Internet of Things describes a major trend that is having lasting effects on society at large. The term itself, "Internet of Things," is used to refer to a variety of ideas, depending on the motivation and background of the speaker. This course will begin by providing a definition of the term. We will talk about how various trends have enabled the Internet of Things and how it changes the way design is done. We will also discuss some of the ramifications that IoT is having on today's society.
In Module 3, we introduced the concept of the Internet of Things at a high level, defining the term and describing its implications. In this module we explore some of the details involved in the design and implementation of IoT devices. Unlike traditional computer-based systems, IoT devices are "embedded" within other devices to provide enhanced functionality without exposing the user to the complexities of a computer. Users interact with the device in a natural way, similar to their interactions with any other object in the world. In this way, an embedded system has an interface that adjusts to the expectations and needs of users. Establishing a natural interface requires that the embedded system interact with the physical world directly through sensors, which read the state of the world, and actuators, which change the state of the world. In this module we will discuss the structure of embedded systems and describe these interactions with the physical world.
IoT devices are implemented using hardware and software components. Dedicated hardware components are used to interface with the physical world and to perform tasks that are more computationally complex. Microcontrollers are used to run software that interprets the inputs and controls the system. This module analyzes the functions of the hardware and software components in the system. The functions of common hardware components are described and the interface between software and hardware through the microcontroller is explained. IoT devices often use an operating system to support the interaction between the software and the microcontroller. We will define the role of an operating system in an IoT device and how an IoT operating system differs from a standard one.
An important aspect of the Internet of Things is that devices are networked in some way, and are often connected to the Internet. Networks allow devices to communicate with other IoT devices and larger cloud-based servers. IoT devices can often be thought of as small parts of a much larger collective system that includes large cloud-based servers. This module will introduce the basics of networking and the Internet protocol in particular. Finally, most IoT devices are connected to the Internet, so understanding the protocols associated with the Internet is important to IoT device design. We will also introduce the concept of Mobile Ad Hoc Network, or MANET, which describes small local networks of IoT devices.
