Hi, * Romain Thouvenin: >I would like to know if/how the propagation time of packets is >simulated in tossim, and how it generally relates to the real world. I >didn't find anything about it on the website but I may have missed it, >I'm not very familiar with the terms.
I'm relaying second hand knowledge: Tossim apparently adds a random delay of a few simulation cycles before a receive event is processed at the receiving node. How this delay is calculated, I don't know. Also, for radio propagation, the delay in the real world will be small. If sending a packet takes, say, 10 ms, and a node 200 m away receives it, the propagation delay is approx. 200 m / (2e8 m/s) = 1 us. So medium propagation can probably be neglected. Hope this helps, Alexander _______________________________________________ Tinyos-help mailing list [email protected] https://mail.millennium.berkeley.edu/cgi-bin/mailman/listinfo/tinyos-help
