OPNET: An Integrated Design Paradigm for Simulations

International audienceIn recent years, a lot of progress has been made in the field of networks and communications; and also in design of simulators. In this paper, we survey and review prominent fields where OPNET has been applied and compare it with other existing simulators. Our work helps beginners and researchers alike in estimating the useful features and limitations of OPNET and the state-of-art in network simulations, modeling and curriculum design. We cover a wide variety of areas of application, to highlight the versatility of applications of simulation tool. The conclusions from the study give valuable directions for further employment of OPNET and also for its extension
