NS3 CODE PROJECTS

NS3 Code Projects offers you complete code support for your project to enhance your project standard and also quality with the help of our proficient experts and versatile developers. We can also say that Code is the soul of the project as it decides the final outcome of any project. If a project is not implemented properly, no one can interpret your ideas as ideas are only transformed into a project. This is the reason, majority of scholars stuck up at the last stage of project phase i.e. Code execution and implementation.

We also offer our complete guidance regarding NS3 Code projects for students, who are in need of a perfect guiding hand. Also, We start our service with novel conceptualization of idea to offer an innovative and ingenious platform for student’s career upliftment. We also end up our project guidance service, when students feel contented and satisfied with our work. Also, We can assure you that our project guidance will upgrade your technical stuff and will fetch you high grades to enhance your academic performance. Approach us, to get our code assistance and also experience our expert’s adeptness.

KNOW ABOUT NS-3

NETWORK SIMULATOR 3 [NS3]:

Discrete event simulator oriented towards networking research and also education
Focused on layer 2-4 of the OSI stack, also which includes IPv6,IPv4 and Next generation[Non-IP] networks.
Open source software also with real time emulation support
Tools used:
- -Netanim[Offline Network animator]
- -Bonnmotion[tool for Mobility pattern generator ]
- -TraceMetrics[Trace file analyzer of NS-3]
- -PyViz[Live simulation visualizer also for NS-3]
- -Pybindgen[also Used to generate python binding for C++/C code]
- -WAF[Building tool] etc

PLATFORM SUPPORT:

-Latest version[NS 3.25]- Added features [Upgraded Wi Fi, new traffic control framework and also Internet Module]
-Operating system support:
- MAC OS X
- Linux[with gcc versions 4.2 to 4.8]
- Windows[Cygwin 1.7]
- FreeBSD[GCC version 4.2 and clang version 3.3]
-NS3 is Installed Using
- Manual installation also using Tarball and Mercurial
- BAKE

LANGUAGE FUNDAMENTALS

-C++[Core Language]:

NS3 libraries can also dynamically or statically linked to C++ main program
It defines the simulation topology and also simulation startup functions
Use of C++ Namespace and also simulation programs are C++ executables

-Python:

Used also as a binding language
C++ is wrapped also using python and it act as a scripting language

SIMULATION STEPS

Define the topology[Use a system of helpers and also containers]
NS3 Module development[Models like UDP, IPv4, LTE etc are also added to the simulation]
Node and Link configuration and also implementation[Set the node attributes and connect them also using links(like point to point link)]
Simulation Execution[Facilitates the overall events and also logs the data requested by the user]
Performance analysis[statistical analysis also using tools like R tool] and graphical visualization[also using tools like Matplotlib, Gnuplot, XGRAPH]
