Simulations of Grant Allocation in NG-PON2 Networks Using OPNET Modeler

Using Opnet Modeler to Analyse Galileo Communication Networks

Galileo is a European initiative to develop and deploy an independent global satellite-based navigation system. It consists of a Medium Earth Orbit sat ellite constellation transmitting navigation signals, a ground segment for monitoring and control of the constellation and for determining and disseminating the navigation messages and integrity warnings through the navigation signals to the use...

Analytical model validation using OPNET Modeler

This paper presents and validates through simulation an analytical model for multihop connections in AMR systems (Automatic Meter Reading). The model is based on a Markov Chain and has been validated with a Monte Carlo Simulation based on OPNET Modeler in order to obtain a verification of the explicit formulas calculated from analytical model. The model is applied to the AMR case where the norm...

AdHoc routing performance study using OPNET Modeler

A wireless Ad Hoc network is formed by a collection of nodes disposed in a dynamic way, without the need for a central node to coordinate them. This is one of the reasons why a great number of routing protocols for Ad Hoc networks are being developed. After the study of a set of them, this paper has subjected four different protocols to different scenario situations, in order to evaluate their ...

Quality of Service in Wireless LAN Using OPNET MODELER

Implementation of Optical CDMA Network Simulation Environment Using OPNET Modeler

Optical CDMA has gained increasing attention as a promising access network technology. This paper presents an optical CDMA network simulation environment based on OPNET modeler, with a focus on the simulation module implementation. We discuss the pipeline structure of optical CDMA transceivers and describe its interface with the physical layer for system integration. We also present the archite...
