Simulation Automation of Wireless Network on Opnet Modeler
2018Today, wireless networks have experienced significant progress, which has given rise to several technologies that coexist with each other in the same environment forming heterogeneous environments. The problem posed by this architecture is the navigation between several networks in a transparent way, hence the appearance of a compromise between ...

Modeling of High Frequency Link Based on OPNET
2009 International Forum on Information Technology and Applications, 2009How to model and simulate high frequency (HF) link is a key and difficult problem in HF communication network simulation system. As an excellent networks simulation software, OPNET provides 14 wireless pipeline stages to support wireless link simulation. However, these pipeline stages are unsuitable for HF link due to its special propagation mode.

Large Sensor Network OPNET Model Debugging
2019A wireless sensor network is a wireless network made up of a number of immobile or mobile sensors which are self-organizing or multi-hopping. Sensor nodes perceive, acquire, handle, and transmit information from the perceived objects covered by the network, and send that information to the sink nodes ultimately.

Large scale border security systems modeling and simulation with OPNET
2017 IEEE 7th Annual Computing and Communication Workshop and Conference (CCWC), 2017Most aliens who manage to get across borders undetected are known to end up in cities, and comprise some of the greatest security challenges a country can face. Safety in cities requires critical security measures that ensure that no aliens operate from across the border to avoid local enforcement.

A comparison of active queue management algorithms using the OPNET Modeler
IEEE Communications Magazine, 2002A number of active queue management algorithms for TCP/IP networks such as random early detection (RED), stabilized RED (SRED), BLUE, and dynamic RED (DRED) have been proposed in the past few years. This article presents a comparative study of these algorithms using simulations.

Modeling Multistandard Wireless Networks in OPNET
2011Future wireless communication is emerging towards one heterogeneous platform. In this new environment wireless access will be provided by multiple radio technologies that are cooperating and complementing one another. The paper investigates the possibilities of developing such a multistandard system using OPNET Modeler.

OPNET-based modeling and simulation of mobile Zigbee sensor networks
Peer-to-Peer Networking and Applications, 2015Modeling and simulation can help to validate and evaluate the performance of wireless sensor networks (WSNs) within specific applications. In order to resolve the issue of the restriction on node mobility in existing Zigbee WSN simulation models, this paper proposes a Zigbee compliant new simulation model using the OPNET simulator.

Implementation of the New Integration Model of Security and QoS for MANET to the OPNET
2011The implementation of the new designed model used to integrating security and Quality of Service (QoS) as one parameter in mobile ad-hoc network (MANET) is introduced and studied in this paper. Security and QoS represent a highly important field of research in MANET and they are still being considered separately with no mechanisms used to establish ...
