Zach in his blog gave out a list of pros and cons of zigbee and 6lowpan
Here is why ZigBee is not competetive, and shouldn’t be compared to 6LoWPAN and IPv6:
- ZigBee = small-scale isolated ad-hoc networking. 6LoWPAN = massively scalable networking as an end-to-end part of the Internet, it is IPv6!
- ZigBee = limited to a single radio standard. 6LoWPAN = applicable to any low-power, low-rate wireless radio (or even wired! See Watteco). IP protocols tie together heterogeneous networks.
- The only good part of ZigBee is application protocol profiles. And guess what, there is an IETF specification for using ZigBee profiles over UDP/IP. http://www.ietf.org/internet-drafts/draft-tolle-cap-00.txt
- ZigBee is not a standard, it is a special interest group. Will it be around in a few years? The IETF produces open, long-lived, standards. IPv6 will be around for 20+ years.
- Large-scale enterprise automation, M2M, metering systems etc. require end-to-end addressing, security, mobility, traffic multiplexing, reusability, maintainability, and web-services which are globally scalable… this is the kind of thing IPv6 was designed for.
I only see one option for ZigBee, and that is to get properly networked. I bet soon we’ll be seeing something called ZigBee/IP 2010.
ZigBee over UDP/IPv6
Personally agreed with Zach, there is no debate that IPv6 prevails in the end, and logically 6LowPan will start to take off followed by IPv6’s rising..
Interestingly Zach envisitions a future zigbee will ultimatly address at the application profile level, rather than working on the networking level, it is possible, only possible…
Never thought that zigbee will give up the network level since a lot of stuff has already shaped, what is more possible is zigbee adopts IP in alternative way, adding support for IP6 while keeping both networking level and application level, even as 6lowpan as network protocol has a lot more merits.. And that comes to the vision of covergence of technologies, again and again..
Anther thing seen today, GE choose Zigbee as low-power network protocol rather than wi – fi
In the race between ZigBee and Wi-Fi for networking energy-aware homes, GE is leaning toward the low-power winner.Utilities around the country have chosen ZigBee as the preferred technology to link smart meters and devices in the home, largely on the strength of its low power requirements and cheaper chipsets compared to Wi-Fi and other technologies built for higher-bandwidth applications.
GE bridges the utility-consumer gap: Consumers today have little more than a monthly utility bill to understand how much power they’re using and how much they’re spending. Compare this to your credit card statements, which you can check almost hourly online. New utility pricing plans, along with inevitable increases in electricity costs, beg for solutions to provide consumers with the information necessary to better manage energy.
