Mastering IOT

By: Colin Dow, Perry Lea

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

WPAN with IP – Thread


Thread is a relatively new networking protocol for IoT and is based on IPV6 (6LoWPAN). Its principal target is home connectivity and home automation. Thread was launched in July of 2014 with the formation of the Thread Group Alliance, which includes companies such as Alphabet (Google holding company), Qualcomm, Samsung, ARM, Silicon Labs, Yale (locks), and Tyco. 

Based on the IEEE 802.15.4 protocol and 6LoWPAN, it has commonality with Zigbee and other 802.15.4 variants, but with a significant difference being Thread is IP addressable. This IP protocol builds on the data and physical layers provided by 802.15.4 and the features such as security and routing from 6LoWPAN. Thread is also mesh-based, making it attractive for home lighting systems with up to 250 devices in a single mesh. The philosophy with Thread is that by enabling IP addressability in the smallest of sensors and home automation systems, one can reduce power because it doesn't need to persist application...
