OPNET is a powerful network design and simulation tool that has gained popularity in industry and academia. However, there exists no known simulation approach on how to deploy a popular real-time network service such as videoconferencing. This paper demonstrates how OPNET can be leveraged to assess the readiness of existing IP networks to support desktop videoconference. To date, OPNET does not...

Based on the study of HLA (High Level Architecture) and OPNET-HLA interface, the dynamic control of simulation process and the real-time update of simulation for LEO (Low-Earth-Orbit) satellite communication system were achieved on multiple computers. In the distributed interactive simulation, a satellite’s location is controlled, then the end-to-end delay time and the routing table of Iridium ...

1 Research Assistant of the Fund of Scientific Research – Flanders (FWO-Vlaanderen) 2 ESAT-Telemic participates in the OPNET University Program for research [7, 8, 9] and educational projects [10, 11, 12]. Abstract OPNET contains a vast amount of node models that represent specific types of networking gear available in the marketplace. These models closely resemble their real-life counterparts ...

In 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 si...

Vehicular Ad hoc Networks (vanet) are a special kind of Mobile Ad-Hoc Networks (manet) adapted to the communications between vehicles. Several specific protocols to vanets have been developed to improve performances and satisfy vehicular application needs. To evaluate a protocol for vanet, some realistic mobility models are needed. Unfortunately, such models are not provided by Opnet Modeler. I...

Pseudo Random Number Generators (PRNG) are the base for stochastic simulations. The usage of good generators is essential for valid simulation results. OPNET Modeler a well-known tool for simulation of communication networks provides a Pseudo Random Number Generator. The extension of OPNET Modeler with external generators and additional statistical evaluation methods that has been performed for...
