Mastering IOT

Overview of this book

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. We’ll begin our journey with an introduction to Raspberry Pi and quickly jump right into Python programming. We’ll learn all concepts through multiple projects, and then reinforce our learnings by creating an IoT robot car. We’ll examine modern sensor systems and focus on what their power and functionality can bring to our system. We’ll also gain insight into cloud and fog architectures, including the OpenFog standards. The Learning Path will conclude by discussing three forms of prevalent attacks and ways to improve the security of our IoT infrastructure. By the end of this Learning Path, we will have traversed the entire spectrum of technologies needed to build a successful IoT system, and will have the confidence to build, secure, and monitor our IoT infrastructure. This Learning Path includes content from the following Packt products: Internet of Things Programming Projects by Colin Dow Internet of Things for Architects by Perry Lea

Summary


This chapter covered a necessary portion of IoT communication. Using IP-based standard communication greatly simplifies design and allows for rapid and easy scaling. Scaling is critical for IoT deployments that reach into thousands or millions of nodes. Using an IP-based transport allows for common tools to simply just work. 6LoWPAN and Thread demonstrate standards that can be applied to traditionally non-IP protocols such as 802.15.4. Both protocols allow for IPv6 addressing and mesh networking to massive IoT networks. 802.11 is a significant and extremely successful protocol that forms the basis of the WLAN, but can also reach into IoT devices and sensors using 802.11ah or transportation systems using 802.11p. The following table contrasts a non-IP traditional protocol to an IP protocol. Typically, the difference will be in power, speed, and range.

The architect needs to balance these parameters to deploy the correct solution:
