The Internet of Things - IP for Smart Objects













My primary focus is to build a network infrastructure for the Smart Grid. I currently work within the Smart Grid BU of Cisco Systems. Cisco recently acquired my startup, Arch Rock Corp, where I was Founding Member and Lead Engineer and led the development of the PhyNet low-power wireless platform, the world's first commercial IPv6/6LoWPAN product and the first of it's kind to receive the IPv6 Ready-Phase 2 (Gold) designation. I participate in the Internet Engineering Task Force (IETF) and IP for Smart Objects (IPSO) Alliance to standardize and promote the use of IP for smart objects.

I have produced (with the help of others) a number of materials over the years and have linked them here for those that want to learn more. I hope you find them useful.

What's New?

Cisco Systems has acquired my company! See what the press is saying:

IP for Smart Objects in Action

Monitoring Vint Cerf's Wine Cellar
Vint Cerf depends on Arch Rock technology to ensure that his wine cellar is maintaining the optimal environment.
Building a Smarter Power Grid
GE and OG&E are working together to build a smarter grid in Oklahoma City. For 6,600 participants of our project, technology like the GE SmartMeter™ is changing the way they use electricity in powerful new ways. Arch Rock provided the complete Home Area Network (HAN) solution, including the In-Home Displays and Smart Thermostats.
Helping Firefighters Save Lives
The Advanced Incident Response System (AIRS) is an IPv6-enabled solution that allows incident response personnel from various local, municipal, and government agencies to communicate seamlessly during an event while minimizing dependencies on the fixed infrastructure of the disaster site. Arch Rock provided the wireless networking technology.

CS194-05 (S'08): The Internet of Everyday Things
In Spring 2008, I helped teach an undergraduate EECS design studio course, called the Internet of Everyday Things. In addition to teaching core networking and embedded computing concepts, the goal was for students to build fun and useful IP-based applications on top of the same IPv6/6LoWPAN kernel developed for my research. The course was amazingly successful. In a matter of weeks, students built a Google Maps/Nordic Trac Cyber-Physical Mashup, Web-Enabled Coffee Pot, and a Smart Refrigerator.
