Research
My research is in the field of sensor networks. I work with Sydney Pang and Wei Zhang who are advised by Rich Wolski.
Check out the slides describing the VOSN system and the paper:RRC

Xbow stargate plus Logitech 4000 webcam vidcat binary which has jpeg library built in is here.To get an image,
1) first load the camera's modules running the script located in /etc/rc2.d/K931loadwebcam
2)run "ln -s /dev/v41/video0 /dev/video0"
3)use the command: "./vidcat vidcat -s 640x480 -p y -f jpeg -d /dev/video0 > test.jpeg"
4)scp the image to a computer for viewing
A version with RRC built in is available. Just email me for source.
Additionally, if you are looking for a C client for TinyOS 1.x that has all the handling of receiving/sending of packets send me an email as well. The client is just the bare bones, and you can fill in whatever additonal code to make it work for you. It would connect to a serial, USB-to-serial, or port connection (for a simulator like DiSens) to a programming board (which talks to a mote via UART). Thus, this is the gateway software running on a PC or laptop. The client does the framing, queuing, crc checks, one has to do for serial communication. There are two threads for processing data and control. The control has the implementation to do acks. For my application I had the data thread do voice communication. At minimum it may help as a reference. See the paper on VOSN for more information.
