Review : Network Modelling and Simulation Tools

2009

Computer network technologies have been growing explosively and the study in computer networks is being a challenging task. To make this task easy, different users, researchers and companies have developed different network modelling and simulation (MS) tools. These network MS tools can be used in education and research as well as practical purposes. They vary with their characteristics. This paper reviews some of the most important network MS tools developed recently. This paper also shows a classification of the tools used in communications networks.

Comparisons between Computer network simulation tools' models are demonstrated in this papers. An integrated tool NeDaSE (network design and simulation environment) has been implemented and using this integrated tool, models are transformed between different network simulationt tools and a comparison between codes of the network models of tools is preformed. The models representation codes of the tools are characterised in this paper. This is the continuation of our previous papers.

A Literature Survey of Network Simulation Tools

2017

In the network research era, it is very difficult to deploy a network very efficiently as it takes too much time as well as money. Network simulation tool is the best source to develop a network as it helps a developer to check the functionality of a network in real environment. Thus simulator reduces the time as well as cost of testing of a network. In this paper, we provide the different simulation tools, their advantages and disadvantages. This survey is a approach to give advantage for those who feel difficulties to select the appropriate network simulator.

A Survey Of Network Modeling And Simulation Tools: Devs Comparison

Speed, hardware, cost, diversity of user demands and interoperability requirements of today's network systems cause several difficulties in network research. In design phase, due to time and cost advantage of modeling and simulation science it is widely used by researchers working on network systems. In order to expedite and simplify the design process, to design and develop network simulation tools is an active research area. Today, many modeling and simulation tools are available in computer networks research and education. In this study, to assist researchers working on computer networks in the selection of modeling and simulation tools, several best-known simulators are selected and compared. Especially to examine the advantages and disadvantages of network simulators used for training purposes, an OSPF protocol implementation was devised to discuss strengths and weaknesses of simulators. At the same time, executing a general purpose DEVS based OSPF model in DEVS-Suite simulator; the advantages of the method are summarized.

A Comparative Analysis of Network Simulation Tools

2010 International Conference on Modeling, Simulation and Visualization Methods (MSV 2010), 2010

Today, simulation has become a fundamental tool for researchers and network administrators to design, debug, improve and fine-tune networks. One of the main problems faced by these specialists when selecting a simulation tool is the variety of options. This converts the selection in a complex and long process. In most cases, the selection of the tool is done without following a suitable process which should include identifying needs, scopes, and constraints of the project. In this paper we studied a group of network simulation tools to guide users during the selection process. We focused on the level of support that these simulation tools can offer to new telecommunications technologies trends, and the amount of effort needed for installation and familiarization. One of the goals of this paper is to help researchers and network administrators to quickly identify which simulator is most suitable for their needs.

A Survey of Network Simulation Tools: Current Status and Future Developments

2008

Abstract In the network research area, it is very costly to deploy a complete test bed containing multiple networked computers, routers and data links to validate and verify a certain network protocol or a specific network algorithm. The network simulators in these circumstances save a lot of money and time in accomplishing this task. Network simulators are also particularly useful in allowing the network designers to test new networking protocols or to change the existing protocols in a controlled and reproducible manner.

Network Simulation Tools Survey

— In the network research area, establishing of network in a real time scenario is very difficult. A single test bed takes a large amount of time and cost. So implementation of a whole network in real world is not easily possible and very costly to. The simulator helps the network developer to check whether the network is able to work in the real time. Thus both the time and cost of testing the functionality of network have been reduced and implementations are made easy. In this paper, we introduce the main features of different simulator and consider their advantages and disadvantages. We hope this survey prove to be a good reference source for those people who feel difficult to select the appropriate network simulators for their research.

Key Features and Optimum Performance of Network Simulators: A Brief Study

In the network area, to establish a network in real time for any experiment is very difficult. To test a simple problem takes a large amount of time and cost. So it is not quite possible to implement the whole network scenario in a real time. There are many tools which helps network developer to test their network scenarios virtually whether the network is able to work in real time environment. The network simulators are used for performance analysis in the field of communication. With the help of these simulation tools both the time and cost of testing the functionality of network have been reduced and implementations are made easy. In this paper, we briefly discuss the main features of different simulators, new developments and also discuss their advantages and disadvantages in the field of network simulation. We hope that the people who face difficulty in selecting a proper suitable network simulation tool in their research this paper is helpful for them.

A Practical Approach of Network Simulation

Detecting and Mitigating Robotic Cyber Security Risks

Communication is a very important area of research in the present era. Expansion of globalization and reduction in the cost of electronic devices has made communication very effective. A large number of researchers from academics and industries are involved in the research on communication and networks. Any novel idea has to be verified on the simulator. A number of simulators are available for network simulations such as Network Simulator (NS2 and NS3), OPNET, NetSim, OMNeT++, REAL, J-Sim and QualNet. NS is an open-source simulation tool that runs on Linux. It is a discreet event simulator for networking research and provides substantial support for simulation of routing, multicast and IP protocols. This chapter provides an overview of NS in a much simpler way. At the completion of this chapter readers will be able to write tcl script to simulate a scenario of network. Every simulation on NS generates a huge trace file; the study of this can be done with the help of AWK script.
