Network Simulator may be the fastest growing technologies in our research culture today. To study of GloMoSim is both exciting and challenging. It is exciting because it presents a wide range of programming techniques that make it possible to solve larger and more complex problems. It is challenging because the richness of C language brings with it many concepts that change the way we approach the protocol design. Because the study of GloMoSim is such a rich subject, you will find that it is not possible to cover all of the material in one term. In fact, GloMoSim is such a rich network simulator that you will find it taught in UG and PG graduate programs and research programs.
