Enhanced ZigBee Smart Energy
• Integration with ZigBee IP stack and PLC
• Exploits the benefits of wireless and wired
• Support for Forward-Thinking Developments
(PHEVs, Distributed Generation, etc.)
• Working closely with IEC, EPRI, AHAM,
ESMIG, and others on requirements
• Other Improvements based
on continuing feedback
and Market needs
• One of the initial 16
on the NIST list for the Smart Grid

Why a ZigBee IP stack?
•
•
•
The United States Congress suggested it in relation
to Stimulus Funding access and US utilities are now
requiring it as part of their future networks.
Offers alternatives not new capabilities
What will be in it?
– MAC – 15.4 2006 with MAC security
– 6lowPAN packet format and fragmentation
– ROLL routing
– Plus other features essential to effective sensor
networks

Smart Energy 2.0 and ZigBee IP Background
• US National Institute of Standards and Technology (NIST)
– Direction on standards selection
• UCA International OpenSG
– OpenHAN System Requirements Specification (SRS)
– Market Requirements Document (MRD) and Use Cases for Smart
Energy 2.0
• ZigBee
– Developing IETF based IP stack for IEEE 802.15.4 based
platforms based on OpenHAN SRS and Smart Energy 2.0 MRD
• HomePlug
– Developing IEEE P1901 compliant powerline carrier solutions:
HomePlug AV and HomePlug SE
• Recognized Standards Development Organizations (SDOs)
– IETF, IEC, IEEE, W3C

ZigBee IP Architecture Overview
• Meets Smart Energy 2.0 MRD:
– “Shall source existing standards from
internationally recognized standards bodies with
preferential treatment given to the following
standards bodies: IEEE, IETF, IEC, ISO, and the
W3C
• Where standards do not exist, new standards shall be
proposed and developed within these organizations “
– “Clean layered architecture”

ZigBee IP Standards Selection
• IEEE 802.15.4-2006 with some extensions proposed in task group 4e
• IETF networking standards:
–
–
–
–
6LowPAN (RFC 4944)
IPv6 (RFC 2460)
UDP, ICMP (probably not TCP)
ROLL (in Internet-Draft form now)
• IEC standards
– 61968 CIM
– Extensions from ZigBee SE and OASIS (harmonized back into the CIM)
• W3C standards
– EXI (probably, though could be another tokenized XML solution)
• Missing technology we are working on in other standards groups:
– Binary HTTP, SOAP over UDP or similar binary web services transport
protocol (though IETF 6LowAPP or Transport Work Group)
– Embedded Service Location Protocol (SLP) (through IETF)
– MAC enhancements (in IEEE 802.15 task group 4e)
– Meter Access Side Communications standard (in IEEE 802.15 task group 4g)

ZigBee Smart Energy 2.0 Development Plan
• MAC/PHY
– IEEE 802.15.4-2006
– HomePlug AV/SE
– Interoperate with any other MAC/PHY (WiFi,
Ethernet, etc.)
• Networking
– IETF standards
• Application
– Aligned with IEC 61968 CIM
– Message syntax defined through XML

ZSE 2.0-- Process Going Forward
• IETF IP networking stack (aligns with PAP 1)
• PAP 3, 4, 9 and 10 align with the IEC 61968 CIM.
ZigBee SE 2.0 and OASIS will create syntax from the
model
• IEEE 802.15.4 aligns with PAP 2
• NIST Phase 3 – Certification (defined at the end of
2009)
– Align ZigBee Smart Energy V2 certification and
interoperability process around NIST approved
certification process

Why ZigBee+Power Line Carrier?
• Simplified installation for new smart
energy applications in large apartment
or commercial buildings with no other
control networks
• Further expansion of the Home Area
Network market by enhancing the ease
of use and commercial viability of Smart
Energy
• Advent of PHEVs in 2010 requires
energy management system to address
technical and business problems
related to charging/discharging, billing,
and access management.
• Common system architecture and
application profile interface for home
energy devices independent of
networking technology
