First you need to get the log files from your testbed experiments. Did you get the logs? The assumption is you have one log file per node. Then you need to run a series of Perl scripts on the logs. You need a few custom Perl libraries and neato to produce the result you see. Because of these dependencies, I haven't posted all those Perl scripts because it most likely won't work on other systems. But here is how you can proceed: 1. Run the parse-ctplogs.pl script on the log files. 2. Do statistics on the output from step 1. For example, if you want to compute delivery ratio for a specific node, you can keep track of sequence numbers received from that node and compute the delivery ratio. If you want to compute churn, you can count the number of times beacons was sent. All these log messages are parsed with parse-ctplogs.pl. Feel free to ask questions as you get going. - om_p _______________________________________________ Tinyos-help mailing list Tinyos-help@millennium.berkeley.edu https://www.millennium.berkeley.edu/cgi-bin/mailman/listinfo/tinyos-help
