Hi, As I read the documents by Dr. Levis (written in 2003), I found that it seems you can not change the BERs during the simulation. For example, if I want to model a time-varying channel instead of static channel, I will need to change the BER during simulation. So far from the documents, a configuration file for channel BERs are used and read during the simulation. I wonder if I change these parameters during the simulation, whether the simulator will notice it and change the BERs accordingly.
The other way mentioned is to use TinyViz, a tool provided by Tinyos. But it can only change BER depending on the change of topology (ie. distance between nodes, etc) and use Gaussian packet loss probability distribution for each distance, which may not fit if other distribution is used. Let me know if you know there is updated information regarding this. Thanks. Baozhi
