NETWORK SIMULATIONS WITH THE NS3 SIMULATOR

     Network Simulations with the NS3 Simulator is our service started for the students who aid for external guidance for projects based on NS3 simulator. We are working with NS3 for the past 7 years and have developed nearly 1000+ projects for students from all over the world. NS3 is an open source simulator used to stimulate both IP and non IP based networks. It is mainly used for research and educational purpose. We have 100+ top professionals working with us, to serve their expertise and knowledge for the career development of young scholars and students. Our Network Simulations with the NS3 Simulator will offer you complete guidance on NS3 simulator. As an initial step towards our guidance, we have provided few basics about NS3; let’s have a glance over it.

NETWORK SIMULATIONS WITH THE NS3 SIMULATOR

Highlights About NS3:

  • Open simulation environment for computer networking research
  • Stable version[NS3 3.25]
  • Programming language Used[C++ with python binding]
  • Platform Support[Linux, MAC OS X, FreeBSD]
  • Offers attribute based system to manage the default and per instance values for simulation parameter
  • Attribute based system is integrated with command line argument processing, XML based or optional based configuration subsystem to manage the configurable default values of the parameter
  • NS3 library is wrapped with python using pybindgen library
  • Memory management[Use reference counting for automatic de-allocation of object]
  • NS3 packet format[Consist of single buffer of bytes and an optional tag containing meta data ]
  • In NS2, output is visualized using NAM while in NS3 output is visualized using an additional package[PyViz-python based real time visualization package]
  • Supports Emulation mode to integrate with real networks
  • Unlike NS2[bi-language system], it requires knowledge about C++ only

-Few Interesting features of NS3:

  • Packets can have virtual zero bytes or dummy bytes
  • No memory is allocated for dummy bytes[virtual zero bytes]
  • Reduces the memory constraint of the simulation
  • Mobility Model is optional
  • New features can be easily added[example: Energy Model]

Supported Modules:

  • LTE Module
  • UAN Models
  • Energy Models
  • WiMax and Wi-Fi Models
  • LR-WPAN Model etc

OVERALL SIMULATION WORKFLOW:

Define the topology:

  • Used to define interrelationship between nodes. [Ns3 has a system of container and helpers to support this]
  • Development of Model[Add models like UDP, IPv4 etc]
  • Node and link configuration step[Set default values]
  • Execution of Simulation[Run the simulation files]
  • Performance analysis of overall system[Using .tr files and tools like R to analyze the data statistically]
  • Graphical visualization support[Using tools like GNUPLOT, Matplotlib, Xgraph]

Network Simulation Example with NS3:

  • On the use of NS3 and SUMO based facing model to evaluated on performance for OLSR and AODV in vanet cloud computing
  • An efficient mechanism of software defined wireless local area network for simulator on op
  • An efficient mechanism of MANET using ns3 for compare real world scenario on routing protocols
  • On the use of content delivery network technique based upon data dissemination by manet
  • A study of p2p networks based on simulation on ddos attacks
