Application of Network Simulator 2

NS 2 Implementation Service

Network Simulator 2 is one of the popularly used simulation tool used for network lab experimentation and research. Sensing a huge demand for projects with the use of this technology, we launched NS2 Implementation services. Needless to say, these services have taken off quite well, and today they are among our most successful programs.

NS 2 Simulation software

This discrete event simulator has transformed the nature of network research. Introduced in 1989 as a variant of REAL network simulator, NS 2 has evolved substantially over the past few years, with brilliant contributions in research work. The major support it offers revolves around the following:

• Routing,
• Transmission control protocols (TCPs), and
• Multicast protocols

NS 2: FAQs

Ques: What should I do after successfully build NS2?

Ans: You need to perform the following steps:

• Put the NS executable path into PATH environment
• Put the otcl path into LD_LIBRARY_PATH environment
• Put the tcl library path into TCL_LIBRARY environment

Ques: What protocols does NS 2 support?

Ans: NS 2 supports all variants of TCP, several forms of multicast, ad-hoc routing protocols, wired networking and propagation models. It also works for data diffusion and satellite.

Ques: I have installed NS 2 successfully, but I'm unable to run the example script in tutorial simple.tcl. It gives errors like:

Ans: In that case, you have to run the script by giving the command: ns simple.tcl and you need to add ns' directory to the environment variable PATH.

Ques: What is a Patch file? How do I apply a Patch file?

Ans: The patch file is a structured text file that consists of a list of differences between one set of files and another. To apply a patch file, get the "patch" program, it ships with Linux. Change into the directory with the source code you want to patch and type "patch /path/to/patch-file.patch"

Ques: I get the segmentation fault while trying to simulate using debugged version of DSR.

Ans: DSR debugged version accepts CMUPriQueue instead of "Queue/DropTail/PriQueue".

What We offer:

Before building an actual network, it is the best way of analysing the impact of various structures. Our NS2 developers in India help and train researchers on how to use the simulators. In case any bugs are found during the implementation process, they are sorted out as quickly as possible. We offer on-going maintenance agreements and training programs so that our clients are constantly in touch with us for effective use of its various functions. We also assist in upgrading of the simulator from version to the current updated version. To know more about our range of NS2 Implementation Service, you can mail us at contact@thesisandcode.com.
