Implementing NS2 Projects
NS2 download
- The newest version of Windows 10 has an additional feature called “Windows Subsystem for Linux” (WSL), also known as “Bash on Ubuntu”. It’s basically an terminal emulator that works like an Ubuntu terminal.
- The Network Simulator - ns-2. Note: The project has migrated these web pages to a wiki.This page can now be found here. Ns is a discrete event simulator targeted at networking research. Ns provides substantial support for simulation of TCP, routing, and multicast protocols over wired and wireless (local and satellite) networks.
In this section we are going to discuss about the basics of ns2.Example program for network simulator 2.Ns2 is a open source software and can be freely downloaded and utilized for Research Purpose.
Quick Intro about NS2 ( Ns2 simulator):
Ns2 simulator for windows10 free download. Ns2-wimax-awg The earlier version of this NS-2 add-on (for OFDM PHY) was developed at NIST. At the WiMAX Forum Ple. Network Simulator 2 (NS2): Installing NS2 On Windows 7 Continued 6. Next screen will ask for your Internet connection type keep it as 'Direct connection' and click next and in next screen choose one site to download the packages and click next.
- NS2 is a discrete event simulator targeted at networking research.
- NS2 is an object oriented simulator, written in C++, with an OTcl interpreter as a frontend.
Ns2 basics:
- NS2 use Tcl language for creating simulation scenario file.
- Network topology, transmission time, using protocol etc are defined in scenario file
Steps involved in creating scenario file:
Step0 Declare Simulator and setting output file
Step1 Setting Node and Link
Step2 Setting Agent
Step3 Setting Application
Step4 Setting Simulation time and schedules
Step5 Declare finish
Sample code for ns2:
This is the sample code for creating random traffic in wireless network.
ns cbrgen.tcl [-type cbr|tcp] [-nn nodes] [-seed seed] [- mc connections] [-rate rate]
What are the return commands are used in ns2:
#define TCL_OK 0
#define TCL_ERROR 1
#define TCL_RETURN 2
#define TCL_BREAK 3
#define TCL_CONTINUE
TCL_OK: it denoted command completes successfully
TCL_ERROR: it implies does not complete successfully. The interpreter will explain thereasons for the error.
TCL_RETURN: after returning from c++, the interpreter exits the current instproc without performing the rest of instproc.
TCL_BREAK: After returning from C++, the interpreter breaks the current loop. This is similar to executing C++ keyword break, but the results prevail to the OTcl domain
TCL_CONTINUE: After returning from C++, the interpreter continues to the next iteration. This is similar to executing C++ keyword continue, but the results prevail to the OTcl domain.
