A Practical Approach of Network Simulation (original) (raw)
Related papers
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.
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...
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.
IRLSim: a general purpose packet level network simulator
2000
Abstract Simulation is the main tool for studying networking protocols before deploying them in a wide scale, or for understanding how they are expected to behave under various conditions. IRLSim is a new packet level network simulator that we developed in the hope to study several Internet protocols.

— 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...
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.
Introduction to Network Simulator NS2
Springer
The objective of this textbook is to act as a primer for NS2 beginners. The book provides information required to install NS2, run simple examples, modify the existing NS2 modules, and create as well as incorporate new modules into NS2. To this end, the details of several built-in NS2 modules are explained in a comprehensive manner.
With the advancement of technology and growth in the wireless industry over time, there seems to be a major change every few years and the recent advancement is Wi-Fi 802.11ac. People are more inclined to use the wireless network within the organisations, campuses and offices. The recent advancement is the fifth generation of Wi-Fi (802.11ac) which has extended the benefits of the previous Wi-Fi (802.11n) with increase in data rate, channel bandwidth, and is more scalable and also the operating frequency. The organisations which started in the late 2012 and early 2013 have a very good chance of deploying these new technologies without any overhead cost or just a minimum amount when compared to other organisations. The brief overview of computer networks has been given in chapter-1 along with the OSI model, network types and topologies. The chapter-2 will discuss the wireless network in detail and their standards. As every network requires security for its proper functioning, it also has to maintain the network availability. The security concerns and types of DoS attacks that can affect the network along with some strategies of prevent such attacks have been discussed in chapter-3. Chapter-4 will briefly illustrate the types of network simulators which are used to simulate a network. The main aim of the project is simulate a wireless network for a small and a medium sized office network and to find the denial of service point which is illustrated in the Chapters-5 and 6 show the simulation of the wireless network with mobile stations and server and wireless network with fixed workstations and server respectively.
