Great article, thanks! With the today's wi-fi device, is there any way to connect to the wi-fi network by itself when it is first brought into the network? Would the new Wi-Fi DIRECT standard help? Saw the Belkin WeMo product, I am wondering how it get linked to the home wireless network. Any idea?

The BT stack (blueZ for the most part) provides a full network stack implementation including profiles. The equivalent of this would not be 802.15.4 - think of this more like the MAC/Phy layer. 6loWPAN is built on top of the 802.15.4 radio to provide packet compression and routing in the network (ROLL/RPL - experimental). The IPv6 network driver talks to the 6loWPAN implementation. What does this mean for Android? It really means you need a dynamically installed 6loWPAN driver with 802.15.4 hardware and you are there.

BTW, we have a 6loWPAN implementation with IPv6, as well.

I think that the conclusions of this article are based on some erroneous assumptions. The most glaring example is that there is absolutely no reason you cannot download a new image and reflash it using any wireless network that has appropriate protocols. 6loWPAN supports this sufficiently. Why do we need an interpreter? It is an option and may be cool but other approaches work as well. Interpreters are inefficient and not so secure. By the time that all the security is added you have Java which requires 1M -3MB of memory to be practical. I think a range of solutions will be provided for some time.

Another company that has a combined SNAP and 6LoWPAN stack is NXP, through their acquisition last year of Jennic. They call it Jennet-IP and they announced recently it will be open-sourced. You might also want to check out: http://www.jennic.com/products/protocol_stacks/jennet-ip

More important than addressing length is security; in particular in the Internet of Things which often lacks human intervention and a cloned device with bad intentions can cause serious issues. As everyone knows both IP addresses and MAC addresses do not meet the uniqueness criterion as they can be modified. If we compare with RFID, most tags (and even readers) have their unique ID in hardware guaranteed by the vendor or by a 3rd party and cloning (with the exception of some older standards) is extremely difficult. In NFC, the optional secure element provides the same security. How can we guarantee that one node is not assigned the same IPv6 address as another node? In the IPv4+MAC world, this is not possible. Therefore nodes will need a third ID which also will need to be unique. Unless there is a technology as well as a trusted third party to guarantee the uniqueness of IPv6 addresses, and making them untamperable, IPv6 will be limited to very few non-critical applications.

Forgive my ignorance Max, but do the existing android phones simply need a new compilation to communicate over 802.15.4 as they can already communicate via Bluetooth (802.14.3)?

Great article. I think Android@Home has a great potential, but the Google's move also raised many issues and questions. The following article may be of interest. http://blog.millennialnet.com/2011/07/13/where-is-google-going-with-the-android-home-initiative/

I made presumption. After more detailed look at SNAP, It looks great. I see lots of potential and also things to improve. We can hope Google buys them and makes SNAP free. SNAP + Android would make lots of Home automation (HA) enthusiasts very happy :) IPv6 is least important in this HA story. We learned to live with IPv4 quite well.HA Control in either case should go trough master software on gateway and i dont see any benefit of my light bulb having IP address, especially not 128bit one :) Thanks for great article!
