In this study, we have a research of the design and implementation of co-simulation platform for wireless networked control systems based on Simulink and OPNET. The real time simulation platform for wireless networked control systems were designed and realized by using Simulink and OPNET. Simulink and OPNET were adopted to simulate the real time control and network performance separately. The c...

As wireless technology is becoming more and more prevalent; security in such networks is becoming a challenging issue and is in great demand. One of the most powerful tools in this area which helps to simulate and evaluate the behaviour of networks and protocols is OPtimised Network Engineering Tool (OPNET). Although OPNET has covered a wide range of models and a variety of protocols, there is ...

In this paper we discuss the network systems support for the OPNET (version 5.1.D) application at the School of Engineering Science at Simon Fraser University (SFU), we describe a research project in wireless data networks using OPNET (version 5.1.D), and we discuss the teaching experiences using OPNET (version 4.0.A) at the University College of the Fraser Valley (UCFV).

Many of the sensors finding their way into sensor networks run a lightweight operating system developed at U.C. Berkeley called TinyOS. This open-source operating system, designed specifically for highly-constrained wireless devices, enables building a variety of applications using highly modular code. Over one hundred groups worldwide, and several company products, use TinyOS. Our main contrib...

For almost a decade, COMSAT Laboratories has been using the OPNET tool for the simulation of multimedia satellite systems. Starting as one of the Beta sites for the first release of OPNET software, we have since applied the OPNET simulation environment to perform system evaluations and trade-offs in a variety of areas related to fixed and mobile multimedia satellite systems. This paper presents...

The Internet is an evolving force that contributes to rapid economic expansion worldwide. However, each newly emerging Internet technology requires rigorous evaluation and testing; a process that often includes simulation and modeling. OPNET Modeler is among the foremost software products for the simulation and modeling of communication protocols and Internet technologies. However, OPNET's cons...

In this paper, we describe the enhancements made to an existing General Packet Radio Service (GPRS) network OPNET model. These enhancements to the existing model are the implementations of the Logical Link Control (LLC) layer, the Base Station Subsystem (BSS), and the cell update procedure. We first present an overview of the GPRS network, the LLC layer, and the existing OPNET model. We then de...

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...
