The IETF (Internet Engineering Task Force) 6LoWPAN (IPv6 over low-power wireless personal-area networks) working group has defined specifications for low-power, low-cost sensor devices. They defined the IPv6 adaptation layer for IEEE 802.15.4 based networks. Ryan introduces the 6LoWPAN protocol stack and explains how to use it as a low-power solution to IoT wireless network systems.
- 6LoWPAN is an open standard by the internet engineering…task force, IETF.…It shares many features of Zigbee networks…in terms of the unlicensed frequency bands,…network topologies, support for low power devices,…data link layer security schemes,…and target applications.…The 6LoWPAN network provides a direct IPv6 support…on top of the IEEE 802.15.4 radio interface.…
The direct IPv6 support…is suitable for a dense 6LoWPAN…because of the large IPv6 address space.…6LoWPAN can make IoT and devices…connect to other IP networks without using…any proxies.…Also, it allows us to use popular tools…and protocols running on top of IP technologies.…Throughout they're used by many communication systems…however in order to support direct IP's we seek to support…there are two major problems to be solved.…
One is the mismatch between IP package size…and the IEEE 802.15.4 package size.…The other is the efficient routing schemes…for mesh networking…which is not directly supported by IEEE 802.15.4…So, the solution is to create a sublayer…
Ryan Hu begins by introducing wireless networking for IoT, and going over the basics of wireless communication and wireless networking. Next, he presents and compares the underlying wireless networking technologies in terms of system architectures, communication paradigms, performance, and use cases. Then, he explains how to integrate various networking technologies into an IoT system. To wrap up, Ryan discusses the use of low-power wireless networking in a typical lighting control system for both smart home and smart city environments.
