6LoWPAN is an acronym of IPv6 over Low-Power Wireless Personal 6lowpan the wireless embedded internet pdf Networks. 6LoWPAN is the name of a concluded working group in the Internet area of the IETF.
The 6LoWPAN concept originated from the idea that “the Internet Protocol could and should be applied even to the smallest devices,” and that low-power devices with limited processing capabilities should be able to participate in the Internet of Things. The 6LoWPAN group has defined encapsulation and header compression mechanisms that allow IPv6 packets to be sent and received over IEEE 802.
IPv4 and IPv6 are the work horses for data delivery for local-area networks, metropolitan area networks, and wide-area networks such as the Internet. 4 devices provide sensing communication-ability in the wireless domain. The inherent natures of the two networks though, are different. The problem statement document is RFC 4919.
The target for IP networking for low-power radio communication is applications that need wireless internet connectivity at lower data rates for devices with very limited form factor. An example is automation and entertainment applications in home, office and factory environments. The header compression mechanisms standardized in RFC6282 can be used to provide header compression of IPv6 packets over such networks. IPv6 is also in use on the smart grid enabling smart meters and other devices to build a micro mesh network before sending the data back to the billing system using the IPv6 backbone.
Some of these networks run over IEEE 802. 4 radios, and therefore use the header compression and fragmentation as specified by RFC6282.
Thread is an effort of over 50 companies to standardize on a closed-documentation, royalty-free protocol running over 6LoWPAN to enable home automation. It is to be launched in the second half of 2015.
The protocol will most directly compete with Z-Wave and Zigbee IP. As with all link-layer mappings of IP, RFC4944 provides a number of functions. Beyond the usual differences between L2 and L3 networks, mapping from the IPv6 network to the IEEE 802.
