An underwater acoustic (UWA) local area network (LAN) is designed and tested using Opnet's Radio Modeler. The network consists of master and sensor nodes that will be deployed in sea with battery powered modems. We modeled the UWA channel using the Radio Transceiver Pipeline stages supplied with Opnet. Since the network nodes are stationary, we assumed that channel is slowly varying and stays c...

. Researchers have proposed a number of co-ordination functions in literature for improving quality of service. Each one is based on different characteristics and properties. In this paper, we evaluate the performance of wireless network using PCF, DCF & EDCF. We perform simulations using OPNET IT GURU Academic Edition simulator. In the performance evaluation of the co-ordination function, the ...

Routing algorithms and the hierarchical three-dimensional grid architecture of satellite-based networks (SN) are presented. The performance of the proposed architecture and the routing algorithms are analyzed. Simulation of the routing algorithm based on the extended OPNET platform is performed. It is shown in simulation that the proposed three-dimensional satellite-based network architecture o...

Military services have an active interest in the use of unmanned aerial vehicles (UAVs) for applications including surveillance and unmanned combat. In the future, UAV swarms will be able to gather intelligence cooperatively without human intervention. Since the physical employment of UAV swarm technology is not yet economical, simulation is often used to explore their design. This paper discus...

In this paper we have discussed and evaluated the comparative analysis of performance of OLSR routing protocol in two different networks with different number of users to find out with which network OLSR shows better performance. We are using OPNET simulator tool for the simulation of networks. Few performance metrics like Delay, throughput, end to end delay, MPR calculations, OLSR performance ...

Networked Control Systems over mobile ad-hoc networks have drawn the attention of the researchers because of its suitability in various ad-hoc applications. This paper presents the investigation of such systems using both real wireless communication and co-simulation of MATLAB and OPNET. The plant and the wireless node models are simulated on a computer by MATLAB and OPNET, respectively. The co...
