Hi all, does anyone know if in TOSSIM, the usage of -rf=lossy brings to lose packets cause of an internal error model? Does anyone know something about how TOSSIM handles this option? because by my side i cannot find any explanation on it (i hope the quite bizarre behaviour of my simulation is related to this internal model, so it would be the error's source..) Thanks, cheers Daniele

In the first one i use only flooding to disseminate information, in the other one a particular coded flooding. During my simulations in TOSSIM i understood it's better to use "random" timers to avoid collisions between motes. However using also quite large backoff intervals, i notice, for example: - i have 4 nodes and in TOSSIM i specify grid topology, -rf=lossy and disc.radius=10. In this way one node can see only 2 neighbours, not 3. Well, even managing large timers, node 2 is not able to forward any packets, but 0,1,3 are able. I don't understand. However, in general, the nodes are not able to forward all packets they receive, and this is strange cause when i receive a packet i save it in a buffer and then i post a task to forward it after a random timer's fired. Can anyone help me? It' s really important! Thanks very much for your availability cheers Daniele _______________________________________________ Tinyos-help mailing list Tinyos-help@Millennium.Berkeley.EDU https://mail.millennium.berkeley.edu/cgi-bin/mailman/listinfo/tinyos-help
