You should read the code for CTP to understand how it determines the parent node and forwards packets to the root. You can find the code at tos/lib/net/ctp. You can look at apps/MultihopOscilloscope to understand how to use CTP. - om_p ___ Tinyos-help mailing list Tinyos-help@millennium.berkeley.edu https://www.millennium.berkeley.edu/cgi-bin/mailman/listinfo/tinyos-help
[Tinyos-help] Pls help me - Help on Multihop
Hi all, I am currently, doing a project on data collection and i doing the last part of the project. The last part of my project is to transmit a packet from child node to a parent node to the base station. To implement this i knw i would have to use the multihop protocol. But I m not really sure how do i implement it. May I know what shld i use CTP or dymo protocol? In order to create the parent nodes do i have to treat the nodes as one of the root collector besides the base station? Currently, what i have done is just forward the packets (from the 3 motes which i am given to work on for my proj) to a base station. How do i treat a node as a parent and do the forwarding to another parent and eventually forward to the base station? Anyone can provide me with enlightments? yours sincerely Brandon _ Join the Fantasy Football club and win cash prizes here! http://fantasyfootball.sg.msn.com___ Tinyos-help mailing list Tinyos-help@millennium.berkeley.edu https://www.millennium.berkeley.edu/cgi-bin/mailman/listinfo/tinyos-help
[Tinyos-help] Pls help on PrinfC and Rssi
Hi all, May I know if the how to download the Rssi demo mentioned in wiki, isit dl from this link? - http://mythicalcomputer.blogspot.com/2008/11/tracking-using-rssi-application-in.html. I would like to ask, if i have -15 rssi value is equal to hw many dbm? Second qn is on the printf. May i know how to patch the my printf library to my tinyos-2.x. I followed the instruction as mentioned in wiki - http://docs.tinyos.net/index.php/The_TinyOS_printf_Library_%282.0.2_Release%29. I m not using the cvs to dl the latest patch so i copied the patch into a text file and place it in my cygwin folder. After which i copied entered the command patch -p0 < tinyos-2.0-printf.patch to patch them. I seems to have patched them, but i cannot use the components PrintfC and its interface in my program. Did i patch correctly? anyone Can guide me?

[Tinyos-help] Unable to load Debug Messages & Radio Model plugins
Hi All, I have successfully installed TinyOS-1.x on my vista machine. I ran the Blink application on TinyViz (using 'tinyviz -run build/pc/main.exe 2' command in opt/tinyos-1.x/apps/Blink directory) and it was running perfectly. When i enabled Debug Messages and Radio Model options on TinyViz, I'm unable to view those plugins (Debug Messages and Radio Model tabs is not getting highlighted). Could you please let me know what could be the issue.

Sounds like it is taking time to find the parent. You might consider using CTP with TinyOS 2.x which finds parents quickly (in a matter of seconds). - om_p ___ Tinyos-help mailing list Tinyos-help@millennium.berkeley.edu https://www.millennium.berkeley.edu/cgi-bin/mailman/listinfo/tinyos-help
[Tinyos-help] Re : MultihopOscilloscope application issues: no...
Dear Paolo This is my first response in this mailing list , so I changed your topology file (i started the number of nodes from ZERO) and the problem that only root's sendDone event occurs, was solved .every node tries to send and sendDone event occurs for any. i wrote a program more simpler that multihopOsc... and here is the result : http://rapidshare.com/files/192160387/result.txt.html and here is the topology file , try it , i think 50% i am wrong , http://rapidshare.com/files/192161026/topo.txt.html let me know what happens.

[Tinyos-help] iris mote 420cc and gps. Changing from high power to low power
ref :iris mote 420cc and gps. Changing from high power to low power Has anyone made a program for the 420cc GPS to start them up take the GPS reading in high power mode then after initial reading go into low power mode. If you have done this could you help me. Some pointers on how to do this? or...Have you made the code available? Currently my 15 mote network only lasts one day with GPS attached before power runs out in High power mode. I need them to last at least a month.
