NS2 Source Code

Procedures to create ns2 programs:

We Assist Engineering Students and Research scholars to implement Ns2 Programs for simulation framework.

• Creating the event scheduler
  • Create event scheduler like set ns [new simulator]
  • Schedule the events $ns at <time> “<event>”
  • Start scheduler $ns run
• Turn on tracing
  • Trace packets on all links
  • Open the NAM trace file and Trace file
  • Must appear immediately after creating scheduler
  • Turn on tracing on specific links
• Creating network :create nodes and link and also queues between those nodes
  • Find out route and setup routing-rtproto
    • Find out unicast routes
    • Multicast routes
    • Broadcast routes
  • Create transport connections-agents
    • Creating TCP and UDP agents
  • Creating traffic
    • Use application on Top of agent
    • Start application
    • Stop application
    • FTP
    • Telnet
    • Web
    • Traffic generator
• Monitoring

Why do u Need NS2 Software?

Setting up a network to do some real experiments is the best way for studying about communication in internet. However, setting a network is not easy and costly.For this reason, a virtual network provided by network simulator is used for experiment in only one computer.NS2 which is free and easy to use is the popular all over the world.

Features of NS2 Software:

• It supports both wired and wireless domain.
• In wired domain the following areas are covered:
  • Full TCP.
  • LANS.
  • Applications like web-caching.
  • Diffserv/intserv.

• Wireless domain areas are,
  • Satellite networking.
  • Ad hoc routing.
  • Directed diffusion.
  • Mobile IP.

• Emulator
  • It can receive and send out live packets from/into the real world.
  • Connect simulator in a real network.
