Applying Akaroa2 for automated simulation length control & on-line statistical error analysis of results in OPNET

Simulation is used for developing and testing different scenarios under controlled and reproducible situations. Proper handling of the initial transient effect for steady state simulations, proper selection of simulation length and proper statistical analysis of results are essential for conducting credible simulations. Akaroa2, a universal controller for quantitative discrete event simulation, has been designed to improve credibility of simulation results. It automatically handles the initial transient effect, carries out statistical analysis of results and controls simulation length by stopping the simulation when the required precision is achieved based on continuous analysis of mean values. Simulation programs can be made to run under Akaroa2 to provide statistically valid results. OPNET is a popular simulator used for carrying out telecommunication and networking related simulations, but it does not provide automated simulation length control and initial transient effect handling. We have developed an interface using OPNET co-simulation capabilities to run OPNET simulations under Akaroa2 control. It will allow the user of OPNET to control the length of simulation on basis of the accuracy of statistical results. OPNET and Akaroa2 are available for free for non-profit research at universities.
