6LoWPAN

6LoWPAN, described in RFC 4944, is the IETF-standardized 802.15.4 link protocol that is able to transport IPv6 packets, and it is the established standard for IP-compatible LR-WPANs. 6LoWPAN makes it possible for embedded systems to access the internet using 802.15.4 interfaces, as long as the nodes implement TCP/IP networking, and the link layer provides mechanisms to transmit and receive full-size IP packets using short LR-WPAN frames. The content of the packet is fragmented and transmitted into consecutive transport units, and optionally the network and transport headers are compressed to reduce the transmission overhead.

There is currently no IPv4 counterpart of the 6LoWPAN standard; however IETF is evaluating proposals adopting ...
