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 – 6LoWPAN


In an effort to bring IP addressability to the smallest and most resource-constrained devices, the concept of 6LoWPAN was formed in 2005. A working group formalized the design in the IETF under the specification RFC 4944 (request for comment) and later updated with RFC 6282 to address header compression and RFC 6775 for neighbor discovery. The consortium is closed, however, the standard is open for anyone to use and implement. 6LoWPAN is an acronym that stands for IPV6 over low power WPANs. The intent is for IP networking over low-power RF communication systems for devices that are power and space constrained and do not need high bandwidth networking services. The protocol can be used with other WPAN communications such as 802.15.4 as well as Bluetooth, sub-1 GHz RF protocols, and power line controller (PLC). The principal advantage of 6LoWPAN is that the simplest of sensors can have IP addressability and act as a network citizen over 3G/4G/LTE/Wi-Fi/Ethernet routers...
