I am new to TinyOS , i want to deploy same number of motes in different grid sizes .
i want to run simulations in TOSSIM on 2D plane. when started simulation a defult grid size is coming , what is that default grid size it is giving? and how can set different grid sizes?
I want to set radio range to 5m, 10m etc., in TOSSIM .How to set these values using (distance)scaling factor facility given in TinyViz?
Any body plz reply.
jaya.

Hello, I too noticed that sometimes my packets were getting dropped by nodes for
no reason so I switched to TossimPacketM supplied along with TOS. This code is
busted but you can get around the problems...
