It is not clear what you are asking. Be specific and detailed. Please put some effort in your questions.

Dear Sir,

 I have executed following command to run with 10 repetitions.  

  

root@varsha-laptop:/home/varsha/omnetpp-4.1/Castalia-3.2/Simulations/BANtest7dec# Castalia -i ./omnetpp18.ini -c ZigBeeMAC,GTSon -o v4.txt -- repeat=10

I observed all 10 output values in v4.txt file. My question is, Why castalia gives 10 different output values for the same input?

Plz clear immediately.

I am still not quite sure what you mean by "same input". I am not even sure you understand the idea of repetitions. Have you read section 3.5.2 of the Castalia Manual?

The idea of repetitions is to run the simulation again with a different random seed (actually a set of different random seeds since we have several random processes in our models). The results of each run will be different  (most likely) since so many things are affected by the various random processes in the models. For example, the shadowing effects of wireless channel will be different and hence communication can be affected.

Did you know this already? If you did, then you are probably asking about something else, and I have not idea what this is.

hello sir When I simulate leach  on different number of nodes  energy consumption decrease as number of nodes increase why not energy consumption increase?please help me
