6LoWPAN 6LoWPAN is an acronym of IPv6 over Low power Wireless Personal Area Networks.[1] 6LoWPAN is the name of a concluded working group in the Internet area of the IETF.[2] The 6LoWPAN concept originated from the idea that "the Internet Protocol could and should be applied even to the smallest devices,"[3] and that low-power devices with limited processing capabilities should be able to participate in the Internet of Things.[4] The 6LoWPAN group has defined encapsulation and header compression mechanisms that allow IPv6 packets to be sent to and received from over IEEE 802.15.4 based networks. The base specification developed by the 6LoWPAN IETF group is RFC 6282. Application areas[edit] The target for IP networking for low-power radio communication are the applications that need wireless internet connectivity at lower data rates for devices with very limited form factor. Functions[edit] As with all link-layer mappings of IP, RFC4944 provides a number of functions. Address resolution Security

IEEE 802.15.4 IEEE 802.15.4 is a standard which specifies the physical layer and media access control for low-rate wireless personal area networks (LR-WPANs). It is maintained by the IEEE 802.15 working group, which has defined it in 2003.[1] It is the basis for the ZigBee,[2] ISA100.11a,[3] WirelessHART, and MiWi specifications, each of which further extends the standard by developing the upper layers which are not defined in IEEE 802.15.4. Alternatively, it can be used with 6LoWPAN and standard Internet protocols to build a wireless embedded Internet. Overview[edit] IEEE standard 802.15.4 intends to offer the fundamental lower network layers of a type of wireless personal area network (WPAN) which focuses on low-cost, low-speed ubiquitous communication between devices (in contrast with other, more end-user oriented approaches, such as Wi-Fi). The basic framework conceives a 10-meter communications range with a transfer rate of 250 kbit/s. Protocol architecture[edit] IEEE 802.15.4 protocol stack
ISA100.11a ISA100.11a is a wireless networking technology standard developed by the International Society of Automation (ISA). The official description is "Wireless Systems for Industrial Automation: Process Control and Related Applications".[1] The ISA100 committee is part of ISA and was formed in 2005 to establish standards and related information that will define procedures for implementing wireless systems in the automation and control environment with a focus on the field level. In 2009, the ISA Automation Standards Compliance Institute established the ISA100 Wireless Compliance Institute. Timeline[edit] References[edit] External links[edit] KNX Logo of the KNX standard KNX is a standardized (EN 50090, ISO/IEC 14543), OSI-based network communications protocol for intelligent buildings. KNX is the successor to, and convergence of, three previous standards: the European Home Systems Protocol (EHS), BâtiBUS, and the European Installation Bus (EIB or Instabus). The KNX standard is administered by the KNX Association. The standard is based on the communication stack of EIB but enlarged with the physical layers, configuration modes and application experience of BatiBUS and EHS. KNX defines several physical communication medias: KNX is designed to be independent of any particular hardware platform. KNX is approved as an open standard to: International standard (ISO/IEC 14543-3)Canadian standard (CSA-ISO/IEC 14543-3)European Standard (CENELEC EN 50090 and CEN EN 13321-1)China Guo Biao (GB/T 20965)[1] Twisted pair using differential signaling with a signaling speed of 9600 bit/s. There are three categories of KNX device:
