Colorado Springs, CO, U.S.A. --- (METERING.COM) --- May 11, 2010 - The successful interoperability of two critical new elements of the IPv6 protocol for small, resource constrained embedded devices, or "smart objects," has been announced by the IPSO Alliance.

The interoperability of RPL, the emerging, IETF-specified IPv6 routing protocol for low power and lossy networks, and of 6LoWPAN-HC, a header compression format for highly efficient IPv6 packet delivery over IEEE 802.15.4 low power wireless personal area networks (WPAN), are key to connecting smart objects such as meters, sensors or control devices, and smart appliances over the internet.
 
"The interoperability of these two elements, running on top of three different media, brings us another step closer to reaching our goal of creating IP-based smart objects," said Geoff Mulligan, chairman of the IPSO Alliance.
 
Both RPL and 6LoWPAN-HC are currently being standardized by the Internet Engineering Task Force (IETF) and are significant components of the smart grid infrastructure that includes advanced metering and energy monitoring. A series of successful interoperability tests with several independent implementations of RPL and of 6LoWPAN-HC were conducted. The RPL tests demonstrated for the first time IPv6 routing in a smart object network running on top of IEEE 802.15.4, Ethernet, and low power powerline communication (PLC).

The IPSO organizations that participated in the implementations of RPL include Arch Rock, Cisco, Sensinode, SICS and Watteco SAS. The IPSO organizations that participated in the 6LoWPAN-HC include Arch Rock, Atmel, Cisco, Jennic, Sensinode, SICS, Sigma Designs and Watteco SAS.

The IPSO Alliance is an association of organizations and individuals that promote the value of using the internet protocol for the networking of smart objects.
