6LoWPAN is an acronym of ''IPv6 over Low power Wireless Personal Area Networks''.〔In (''6LoWPAN: The Embedded Internet'' ) (Wiley, 2009), Shelby and Bormann redefine the 6LoWPAN acronym as "IPv6 over lowpower wireless area networks," arguing that "Personal" is no longer relevant to the technology.〕 6LoWPAN is the name of a concluded working group in the Internet area of the IETF.〔(http://datatracker.ietf.org/wg/6lowpan/ )〕 The 6LoWPAN concept originated from the idea that "the Internet Protocol could and should be applied even to the smallest devices,"〔Mulligan, Geoff, ("The 6LoWPAN architecture" ), EmNets '07: Proceedings of the 4th workshop on Embedded networked sensors, ''ACM'', 2007〕 and that low-power devices with limited processing capabilities should be able to participate in the Internet of Things.〔Zach Shelby and Carsten Bormann, ("6LoWPAN: The wireless embedded Internet - Part 1: Why 6LoWPAN?" ) ''EE Times'', May 23, 2011 〕 The 6LoWPAN group has defined encapsulation and header compression mechanisms that allow IPv6 packets to be sent and received over IEEE 802.15.4 based networks. 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. Likewise, IEEE 802.15.4 devices provide sensing communication-ability in the wireless domain. The inherent natures of the two networks though, are different. The base specification developed by the 6LoWPAN IETF group is RFC 4944 (updated by RFC 6282 with header compression, and by RFC 6775 with neighbor discovery optimizations). The problem statement document is RFC 4919. ==Application areas== The target for IP networking for low-power radio communication are 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 802.15.4 radios, and therefore use the header compression and fragmentation as specified by RFC6282. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「6LoWPAN」の詳細全文を読む スポンサード リンク
