NS2 PROGRAMS

      Ns2 Programs are highly used in the recent time due to the need for simulation. By using simulators like Ns2, we can mimic the real network scenario. We can, in short say that Ns2 programs are used to implement both wired networks and wireless networks.  It is used in all major domains like Mobile Adhoc network, Wireless sensor network, social sensor network etc. We cannot limit the usage of simulation tool to any perfect domain. In general, we can say that we can create wired network using “n” number of nodes while in wireless networks, we need to specify the number of nodes as we can have only fixed number of nodes. To code using Ns2 Programs, we use scripting languages like TCL (Tool Command Language), C++, Object Oriented Tool Command Language (OTCL) etc.

     Modeling in Ns2 involves nodes and node configuration. Any two nodes in a simulation environment is connected using duplex link and following are the link characteristic which we exploit:

  • Bandwidth
  • Delay
  • Queue type

 To configure the nodes, we can make use of the following components like

  • Medium Access Control protocol
  • Networking Interface
  • Radio Propagation Model
  • Interface Queue and link layer
  • Adhoc routing protocol
  • Channel and topology object
  • Antenna type

   These are the basics of Ns2, which we need to know before we start implementation in Ns2. Students need not to worry about the implementation or how to learn a vast simulation tool. We have 7 years experience in this field and we have worked with almost all top universities in the world. We have tie up with many colleges where we guide the scholars and many faculties. We conduct regular workshops on this field as it is an evergreen area to explore and learn. Our students are the best tutors for Ns 2 codes and programs as we have made our students to explore this filed.

 Our developers have most newfangled and innovative ideas to explore further in the field of Ns2. If we take an example of network routing protocols, we work on all the major routing protocols which utilizes Ns2 programs like:

  • Modified Ad hoc on-demand Distance vector
  • Particle Swarm Optimization
  • Ad hoc on-demand distance vector(AODV)
  • Blue star and Bluetooth
  • Low energy adaptive clustering hierarchy
  • Destination Sequence Distance vector(DSDV)
  • Dynamic Source routing

 

     Above mentioned are few basic routing protocols used in networking. Our developers use these basic routing protocols to explore further about the way of how to prevent attacks, link life time, energy concept etc. Like this, we consider each and every concept in networking which can be best coded using Ns2.  We believe in finding the most unexplored ideas from the basic concepts. This is the reason why we stand as best and always will be the best as our knowledge is incomparable.
