This document aims to survey three of the currently available and widely used tools, in the field of simulation and modelling of communication systems. The surveys have been written by different team members, hence he difference in style between each tool. Unfortunately the amount of information available is not constant for all of the three tools, which resulted in the non homogenous flow of the document. As questions answered for one tool, will most likely not be the same as the any of the other tools.
Architecture, design and source code comparison of ns-2 and ns-3 network simulators
2010
Ns-2 and its successor ns-3 are discrete-event simulators. Ns-3 is still under development, but offers some interesting characteristics for developers while ns-2 still has a big user base. This paper remarks current differences between both tools from developers point of view. Leaving performance and resources consumption aside, technical issues described in the present paper might help to choose one or another alternative depending of simulation and project management requirements.

— Due to growth of computer networks and complex scenarios the role of Network simulators in research field cannot be ignored. Simulators are useful tools when one wants to consider time and resources, implementation of new security solutions, performance estimation etc. it provides a virtual environment for an assortment of desirable features such as modeling a network based on a specific criteria and analyzing its performance under different scenarios. The newly proposed network simulator NS-3 supports coupling, interoperability, good memory management, debugging of split language objects, coding in C++ and object oriented concepts, as well as supports models supported by NS-2 and most suitable for wireless networks. The primary purpose of this paper is to compare and review this new simulator, as well as find its advantages in the field of research and how it is different from others. We also discuss the current demand of industry as well proposed a framework for a simulator whic...
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.
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 Bridge: Bridging Applications to Network Simulators
Proceedings of the 19th ACM International Symposium on QoS and Security for Wireless and Mobile Networks
Network simulators have been widely used to test and benchmark communication networks, their protocols and services. While new simulators have been developed to account for new technologies and standards, adapting and developing existing, popular network simulators to cope with the everincreasing number and diversity of distributed applications is considerably more challenging. To fill this gap, this paper introduces the Network Simulation Bridge, or NSB for short, a simple, low-overhead pipeline consisting of a message server and client interface libraries that bridge together applications and network simulators. NSB is application-, network simulator-, and platform-agnostic and uses a "plug-and-play" approach which allows it to integrate any application frontend with any network simulator back-end. We showcase NSB by using it to integrate two different distributed applications with the OMNeT++ network simulator. Our performance evaluation confirms that NSB incurs relatively low overhead and exhibits adequate scalability. We open-source the NSB pipeline and its APIs through a publicly available repository.
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.
Discrete Event Simulator for Communication Networks
Discrete event simulation is widely used as a simulation method. The communication networks can become very complex and time consuming to simulate. The objective of the OSsim toolset is the development of a network simulation and analysis package which makes use of technologies from the area of distributed computing, clientserver architectures and object oriented programming. One of the key issues of the design is high performance of the overall system, making possible the modelling and the simulation of complex networks.
A Study on Large Scale Network Simulators
Simulation of network is a very complex task. Network simulation is a modern technique used to analyze the behavior of the network. Simulation method analyzes the behavior of large, complex and highly volatile system. Network simulator software predicts the behavior of a network. It allows the designer to test new networking protocol and change the existing protocol. Through network simulator a program controls the behavior of the network by calculating the interactions of different network entities using various mathematical formulae. The behavior of the network and the various applications and services it supports can then be observed in a test lab. Under different conditions the attributes of the environment can be modified in a controlled manner to assess how the network would behave. In simulators, the computer network is typically modeled with devices, links, applications, etc. and the performance is then analyzed. Simulators usually support the most popular protocols and netw...
