A Survey of Network Simulation Tools: Current Status and Future Development A Survey of Network Simulation Tools: Current Status and Future Developments Jianli Pan, (A project report written under the guidance of ) 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. In this paper, we present a comprehensive survey on current network simulators. We introduce their main features, consider their advantages and disadvantages, and discuss the current and future developments. We hope this survey to be a good reference source for those who feel difficult to find the appropriate network simulators for their research or practical requirements.

Introduction Simulation is a very important modern technology. It can be applied to different science, engineering, or other application fields for different purposes. Computer assisted simulation can model hypothetical and real-life objects or activities on a computer so that it can be studied to see how the system function. Different variables can be used to predict the behavior of the system. Computer simulation can be used to assist the modeling and analysis in many natural systems. Typical application areas include physics, chemistry, biology, and human-involved systems in economics, finance or even social science. Other important applications are in the engineering such as civil engineering, structural engineering, mechanical engineering, and computer engineering. Adobe Illustrator Cs6 Portable.

Application of simulation technology into networking area such as network traffic simulation, however, is relatively new. For network simulation, more specifically, it means that the computer assisted simulation technologies are being applied in the simulation of networking algorithms or systems by using software engineering.
