I am running TOSSIM on redhat linux. I am simulating a network of nodes that are communicating and performing some distributed computation. I am getting very different simulation results on every run. I am not using random numbers exlpicitly in my simulation. I don't know if in TOSSIM code random numbers are used for modeling communication or other things that may be affecting my results. Is the randomness in the results due noise (setNoise) and link gain or could it be something else? I have tried to remove noise (by not having any setNoise statements) and set the link gain to 0.0 but that does not change the non-determinism in the results. Also I observed that all the sent packets are not being received by the probable receivers. There is packet loss and on every run different packets (seems randomly) are getting lost. This may be a source of randomness in the results. How can I make sure that there is no packet loss or is there something else that can resolve my problem?
