Simulation in ns2

Simulation in ns2 offering the final year projects for the B.E, B.Tech, M.E, M.Tech students. Apart from that we are also providing the Phd projects for the Phd scholars for their thesis preparation. The student reputation also is maximized in every year because of our team work and also dedication.

This can be achieved because of our service reliability, on time delivery of projects and our project quality The nodes on the internet (routers) continually learn what connections other nodes also available in Simulation in Ns2.

Because the individual nodes also free to move with a mobile network perhaps this information exchange should happen at also a higher frequency.

MANET

The Simulation is also getting a reasonably good idea on MANET. Eventually, MANET will be used of how to mobile devices that form a peer-to-peer network. The exchange of data or data also to the telecom network or channel through speech when there is no other route is available. The end users could under certain conditions bypass commercial networks (as when you are standing next to each other).

Furthermore, Simulation technology could generate interesting new business models. The MANET can also surely add something to the possibilities of the currently available technologies such as 3G (UMTS and also  by products) for file sharing and also other peer-to-peer services which is used in Simulation in Ns2.

The routing mechanism designed for mobile nodes also required by the multi hop operation. An Internet access mechanism is also used in Simulation in Ns2. And also An address allocation mechanism is required by the Self configuring networks.

Obviously, the final impact strongly relies on the way in which both the world of telecommunications and also the hardware suppliers will act on its appearance on the scene and the MANet itself as a technology is still young.

The Simulation refers the Dynamic network analysis (DNA). The different kinds of analysis is used in Simulation in Ns2 which also Dynamic network analysis (DNA) an emergent scientific field that brings together traditional social network analysis (SNA), link analysis (LA), social simulation and also multi-agent systems (MAS) within network science and network theory.

DNA

An interaction of social features conditioning structure and behavior of networks takes into account is the main difference of DNA to SNA is that DNA.There also two aspects of field is used in Ns2. The statistical analysis of DNA data is the first field on Simulation.

The utilization of simulation to address issues of network dynamics is the second field. The DNA networks larger, dynamic, and also multi-mode, multi-plex networks, and also may contain varying levels of uncertainty and also it’s varying from traditional social networks.

# define options

Set the channel type is also a first step:

set val(chan) Channel/WirelessChannel;# channel type

set val(prop) Propagation/TwoRayGround ;# radio-propagation model

set val(ant) Antenna/OmniAntenna ;# Antenna type

set val(ll)    LL;# Link layer type

set val(ifq)   Queue/DropTail/PriQueue;# Interface queue type

set val(ifqlen) 50;# max packet in ifq

set val(netif)   Phy/WirelessPhy;# network interface type

set val(mac)   Mac/802_11;# MAC type

set val(rp)       DSDV ;# ad-hoc routing protocol

set val(nn)       5;# number of mobile nodes

# Create simulator

The creation of network simulator is the first step of Simulation in Ns2.

set ns_   [new Simulator]

# Set up trace file

$ns_ use-newtrace

set tracefd [open simple.tr w]

$ns_ trace-all $tracefd

# Create the “general operations director”

# Used internally by MAC layer: must create!

create-god $val(nn)

# Create and configure topography (used for mobile scenarios)

set topo [new Topography]

# 1000x1000m terrain

$topo load_flatgrid 1000 1000
