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

Hi all,
in my project i simulate 2 kinds of wireless network. 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
