NS NAM PROJECTS

NS NAM Projects offers a guiding platform for research scholars and student to accomplish their project with the help of our renowned experts. We are serving students for the past 10 years and have served nearly 1000+ students worldwide. We offer complete training plus project for students, who feel they are beginners in NS-2. Our guidance offers all round support for NS2 based project, assignments and lab cycles. You may think that why we have focused on NS projects here.

It is simple to answer, if you are taking a project in NS2, NAM is one of the major components, which you must know well. NAM [Network animator] in NS2 is used to provide visual interpretation of the overall network created. It can be executed directly from the TCL script. It is used to provide information’s like throughput, number of packets etc and offers graphical user interface to NS2. As a further step to explore NAM, let’s have a glance over the Significant features of NS-2 NAM.

HIGHLIGHTS ABOUT NAM

Animation tool for graphical representation of real world packet traces and network traces.
Extended NAM Editor[Allows graphical creation of NS2 Script, works under Linux operating system]
- -Used to integrate with the existing topology generator
- -Used to define new node types
- -Allows the instantiation of agents for a given node
- -Used to define new node types
- -Supports simulation of web cache systems
- -Allows visualization and localization of a set of nodes on large network topologies.
NAM Trace file:

Syntax to creating a nam trace file,

Set nssim [open First.nam w]

$ns namtrace-all $ nssim

Add lookup table

exec nssim result.nam & // To execute nam on trace files

exit 0

NAM trace file look up table:

We are going to list all the nam trace event codes and flags associated with it.
