David Ayers, Sensus vice president of engineering, says his company “is proud to take a leadership role in helping to further the use of IP for networking solutions. As the foremost network layer protocol for enabling multiple applications, IP further secures the role of advanced metering infrastructure (AMI) networks as a key component of the smart grid.”
IPSO reports that for six months it will “conduct a series of interoperability tests at the IP layer, running both within a single PHY/MAC as well as demonstrating interoperability across multiple PHY/MAC layers.
The IPSO Alliance has also presented a new routing standard called RPL. An IP routing protocol designed for IPv6 smart object networks RPL has been approved by the Internet Engineering Task Force (IETF) as an official international standard.
RPL took three years to develop. Contributors included a number of IPSO members and routing experts such as Dust Networks, Ember, Sigma Design and Cisco. Earlier in 2011, Cisco, Sensinode, SICS, and Watteco—all IPSO members— successfully conducted interoperability tests on an early version of the protocol that was instrumental in the course of the standardization performed by the IETF.
JP Vasseur, Cisco Fellow and chair of the IPSO Technology Advisory Board, explains, “This is a key milestone for the IPSO Alliance and for the future of the Internet of Things. RPL is a significant component today for IP Smart Object networks, including smart grid infrastructure.”
The IETF has also completed the draft of the 6LoWPAN-HC, a header compression format for IPv6 packet delivery over IEEE® 802.15.4 low-power wireless personal area networks (WPAN). This is vital to connecting smart objects such as meters, sensors or control devices, and smart appliances over the Internet.
The IPSO Alliance is the primary advocate for IP networked devices for use in energy, consumer, healthcare and industrial applications. Membership is open to any organization supporting an IP-based approach to connecting smart objects. For more information, visit www.ipso-alliance.org.
