Simulation Analysis

 

Data is collected during the simulation. The data collection is performed in two ways: updating WATCH variables (see OMNeT++ User Manual about WATCH) or outputting data to files. There're total 33 WATCHable variables and 31 types of output files generated for user to analysis during or after the simulation. Table 1 summarizes the output files and table 2-31 details each output data. Table 32 gives the details about the WATCH variables. User is suggested to check the Modules page for better understanding of the data collected.
