CODE FOR NS2 SIMULATOR PROJECTS

   Code for Ns2 Simulator Projects is our best way to support the budding scholars, as everyone can work on theoretical concepts but only few can work on implementation part. We have world class developers with us, who imparts their code efficiency into your project to make it an effective project. We never take any work with comfort; we feel that even if we provide a sample program to our students, it must reflect our work standard. We never compromise with our standard as we have our own unique and standard approach, which has made us world no.1 institute today. Our Code for Ns2 Simulator Projects has served plenty of students worldwide. You can also approach us for your project; we will take your complete project responsibility and enhance your grade with our code efficiency.

CODE FOR NS2 SIMULATOR PROJECTS

     Code for Ns2 Simulator Projects offers you complete code support for your projects, assignments and research work. We create a learning atmosphere for you, where you can learn Ns2 along with your project. We support line by line code explanation for your project to make you clear with your concept. As an initial step towards our code support, we have given a sample Ns2 code, which explains about the basic code structure in Ns2. We have provided basic code for node creation, its location setting and overall node movement. It is the basic code used in all the Ns2 simulation project. Let’s have a glance over it.

LEARN ABOUT NS2 BASIC CODE:

    Every project in Ns2 is initiated by the construction of mobile nodes. It can be wireless simulation or wired simulation based on the project selected. In wired networks, nodes are static in nature while in wireless networks nodes are dynamic and can move from place to another. Number of nodes can be increased as per the needs of the network. General Syntax for node creation

                              Set node 0….n [$ns node]

In general, a mobile node has four significant network components:

  • Interface Queue
  • Link layer object
  • MAC Layer
  • PHY Layer-Net Interface[Wireless channel through, which transmission takes between nodes]

Basic Code in NS2 :

 

set node0 [$ns node] \” Nodes Creation \””

set node1 [$ns node]

set node2 [$ns node]

set node3 [$ns node]

set node4 [$ns node]

Phy/WirelessPhy set bandwidth 250mb

#$ns at 0.0 “$ns trace-annotate \”Mobile Node Movements\””

for {set i 0} {$i < $val(nn) }

{

incr i

}

{

$node_($i) color blue

}

for {set i 0}

{

$i < $val(nn)

}

{

incr i

}

{

$node_($i) color blue

$ns at 0.0 “$node_($i) color black”

}

#$ns at 18 “$node_(0) color red” \”setting initial position\””

for {set i 0}

{

$i < $val(nn)}

{ incr i}

{$ns initial_node_pos $node_($i) 20}

#$ns at $val(stop) “$ns nam-end-wireless $val(stop)”

$ns at $val(stop) “stop”

$ns at 130.01 “puts \”End simulation\” ;

$ns halt”

proc stop {} {

global ns tracefd namtrace

$ns flush-trace

close $tracefd

close $namtrace

exec xgraph Performance.tr -x nodes -y Performance &

exec nam Smart_Grid_Network_Topology.nam &

}
$ns run

 

     We have provided a sample code in Ns2, in which we have initialised five nodes and showed how the nodes move and set their location. This is the base code, used in all the Ns2 simulation projects. This will give you an idea about how to code in Ns2.

     Let’s see another most important aspect about mobile node i.e. energy modelling. When a node moves from one place to another, it dissipates certain amount of energy. In Ns2, we can assign initial energy parameter to each node, which will be reduced, once the nodes start moving.

Energy Model for Mobile Nodes:   

 

$ns node-config  -energyModel EnergyModel \

-initialEnergy 1000 \

-txPower 1.75 \

-rxPower 1.75 \

-idlePower 0.0 \

#sensePower 0.0

for {set i 0}

{

$i < $val(nn)

}

{

incr i

}

{

set node_($i) [$ns node]

}

 

    This is just a part of Ns2 codes, which are used in all projects. We work on both wired and wireless simulation projects in Ns2. Here, we have provided a sample basic code in Ns2 for the beginners to know about Ns2 coding. You can approach us for any kind of code support in Ns2; it can be a complex code, project code, code for assignments or lab cycles etc. Send your topic along with your need; we will back to you with your code and solution.
