NS3 SIMULATOR

NS3 simulator is designed as a set of libraries that can be combined together and also with other external software libraries.  While some simulation platforms provide users with a single, integrated graphical user interface environment in which all tasks are carried out, NS3 simulator is more modular in this regard

 

NS3  Simulator Relationship with NS-2:

  • Possible to construct hybrid simulation using NS3.
  • Use different level of abstraction.
  • Random number generators, OLSR, error models, recent WiFi physical models all are already ported to NS3.
  • OTcl and split-implementatioNS3 models are used.
ARCHITECTURE OF NS3 SIMULATOR

Features of NS3 simulator:

  • Packets contain real network bytes.
  • Use real IP address for simulation.
  • Multiple interfaces per node.
  • Bsd-like sockets.

 

Steps involved in simulating program in ns3 simulator:

  • Create a bunch of C++ objects.
  • Configure and interconnect them.
  • Each object creates events with Simulator::Schedule.
  • Call Simulator::Run to execute all events.

Ns-3 is open-source, and the project strives to maintain an open environment for researchers to contribute and share their software.

 

Goals of ns3 simulator:

  • Help to improve the technical rigor of network simulation practice
  • Build and maintain a simulation core aligned with the needs of the research community

 

Basic models in ns3 simulator:

  • Various packet routings like AODV, OLSR, Nix-Vector, static and global link state
  • Supports mobility models
  • Use devices like Wi-Fi, WIMAX, CSMA, Bridge and Point-to-Point etc
  • Error models and queues
  • Applications such as echo server and traffic generators
