Hi everyone, I am using tinyos-2.x and compiling for a micaz platform in TOSSIM. I have a 8 node topology and when I am running my program there is a lot of broadcasting. But there seems to be heavy packet loss in TOSSIM. Is there a way to have no packet loss??? 1. I thought in simulations we can have ideal to near-ideal conditions ......thus is there a noise.txt model I can use off the shelf that would give me this(no packet loss). 2. I have a very simple scenario. There are 8 nodes. Node 1 at time t=0 broadcasts a message. But only a few nodes out of 7 get the message. In this case there cant be any collisions cause there is only 1 transmitter. Thus I am surprised that there is packet loss. Is there a way to get around this?
Even with perfect links (no noise) you can still have losses due to collisions. If only node 1 sends a packet at t=0 and it has links with all the other 7 nodes then all of them should receive them. If all the 7 also try to send a packet at t=0 you should see some losses.
