Data needs to move in the IoT. Learn how the TCP/IP stack provides interoperability and how protocols such as Bluetooth, ZigBee, and 6LoWPAN are instrumental in moving data in the IoT.
- [Instructor] A protocol suite…is a group of interrelated protocols…that help ensure interoperability between network devices.…One of the most common network protocol suites…is the internet suite Transmission Control Protocol…Internet Protocol, or TCP/IP.…The four layer TCP/IP model has the following layers:…The application layer,…which initiates communication on the network;…the transport layer transports data;…the internet layer is responsible…for addressing and routing;…and the network access layer moves data onto the network.…
In general, over time, there have not been…many significant changes for most protocols.…However, the internet protocol had to change,…mainly due to a lack of address space.…Although we typically think of the internet protocol…and IPv6 in particular…as an essential component for the IoT,…not every device needs an IP address.…The fact is, these tiny devices…are not suited for communication…that requires customized control and prioritization.…
IoT devices that ensure industrial control…and home automation rely on a mesh topology…

4/24/2017Lisa Bock kicks off the course with an overview of IoT, and the types of IoT devices designed to improve the quality of life in homes and businesses. Lisa covers different networks that range in size and purpose—LANS, WANS and PANS—and explains how businesses invest heavily in IoT in order to keep a competitive edge, going into IoT developments in automobiles, building automation, and the medical field. She then evaluates consumer devices, such as wearables and mobile devices. Plus, she discusses zero-configuration networking, service discovery, designing IoT security, and more.
