Abstract—Simulation procedures became fashionable among computers and telecommunications network researchers and developers round the world. This quality is owing to the provision of assorted innovative and powerful simulation packages, and owing to the pliability within the construction and validation of models bestowed by imagination
For selecting AN acceptable network machine for a simulation task, it's vital to own smart information of the simulation tools accessible, in conjunction with their strengths and weaknesses. It’s conjointly vital to confirm that the results generated by the simulators are valid and credible.
The purpose of this paper is to survey and compare network simulators so that researchers can help select the most importantly acceptable simulation tool. We compare the support type of network simulators, preparation mode, network troubleshooting and protocols. We tend to discuss machine analysis methodologies and techniques, and supply tips for best follow in network simulation.

Key Words: Network simulator, simulation methodology, parallel simulation.

I. INTRODUCTION

Network simulation methodology is usually wont to verify analytical models, generalize the ministration results, value the performance of latest protocols that are being developed, in addition on compare the prevailing protocols. However, there is also a possible drawback once mistreatment simulation in testing protocols as a result of the results generated by a machine might not be essentially correct or representative. To beat this drawback, it's vital for network researchers and developers to use a reputable simulation tool that is simple to use; additional versatile in model development, modification and validation; and incorporates acceptable analysis of simulation output information, pseudo-random range generators, and applied mathematics accuracy of the simulation results. To pick out a reputable machine for a simulation task, it's additionally vital to possess sensible information of the on the market simulation tools, at the side of their relative strengths and weaknesses. These aspects of credible simulation studies are counseled by leading simulation researchers.

II. A SURVEY OF EXISTING NETWORK SIMULATORS

While numerous simulators exist for building a spread of network models, we tend to compare ten fashionable network simulators lightness their strengths and weaknesses. These simulators were selected supported their quality, revealed results, and attention-grabbing characteristics and options.

i.OPNET Optimized Network Engineering Tool (OPNET) is a discrete event, object-oriented, general purpose network simulator. It provides a comprehensive development environment for the specification, simulation and performance analysis of computer and data communication networks. OPNET is a commercial network simulation package...
