Something is bothering me. I keep hearing that ZigBee and 6LoWPANare competing technologies. The ZigBee Alliance has taken a stand to force such a confrontation. Its like comparing apples and, well, New York
6LoWPAN = IPv6 = The Internet
Think about it. The Internet… the most successfull, innovative, massive network ever created. Now what was that Zig thing called again? Does anyone even remember the proprietary, link-specific networking protocols from the 90s?
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.
