I've been thinking about the project you mentioned yesterday. It seems
like a valuable, cool idea. At the same time consumer products are a
highly competitive area.
I notice a company called Silent Call (silentcall.com) that has
wireless products for sensing and notifying. Given that there is at
least one company doing something similar to what you are thinking, I
would think about how to do it differently.
Sensing: I wonder if it would be possible to install a generic
listening device in important rooms, and then interpret the nature of
the sound via signal processing? What is the accuracy of something
like this? Could the system be trained on certain sounds? I see the
Silent Call people have a generic monitor.
Another option is to look down the road to Zigbee or ZWave home
automation. Are there any prototypes or specifications for interfacing
to appliances?
Internal communication: Besides Zigbee, Wifi seems like an easy way to
get a signal to an actuator.
That's all I can think of for now.
Good luck,
Ken
I know where you're coming from. It took me most of last summer to
talk myself out of the original idea I had for my project. :-)
At the same time, I wouldn't say that you're trying to fit the network
to your problem. As I understand it, the ZigBee project is highly
focused on home automation. It will take a while for it to become
popular, if it ever does, but it ought to be mature enough now for
this sort of research.
Here is a recent article from IEEE Spectrum: http://
www.spectrum.ieee.org/oct06/4666. One of the authors is local:
JON ADAMS is director of radio technology at Freescale Semiconductor
in Tempe, Ariz.
There's no harm in writing to him about your idea. Who knows what
you'll find out. These companies are always looking for smart CS
students, too.

The publications page references a paper describing a routing protocol
for it:

It also really gets away from my initial idea of something that could actually really be a real product and soon... something affordable and practical, that's not a pain to install (no ripping up the walls or carpets).

I was struck by the idea we covered last week of using a bus to pick up news or some sort of data like that, and transporting that data to a rural location where it would automatically download to an access point there. Sort of a way to get around bad network connectivity. However I don't think that idea in itself is practical because rural locations can use 56k modem, satellite or cellular service (like Sprint Broadband).
