WIFI NETWORK SIMULATOR NS2 PROJECTS is one of prime service started with a motive to serve the budding students with our vast experience and expertise. In this Wi-Fi stands for Wireless fidelity [based on 802.11 standards], is one of the hottest research issues in the midst of scholars and students. Wi-Fi technology operates at a frequency of 2.4 GHz and uses radio communication channel. Majority of scholars opt NS2 Simulator as a development platform also for Wi-Fi Networks due to its advanced functionalities and also cost effective solution.

We have developed nearly 1000+ Wi-Fi projects also for students from all over the world. Also, We are proud to say that our students are satisfied with our quality work with an on time project delivery focus. You can also avail our service by clicking one mail/call to us. We will be back to you with our research team to serve your project needs at your flexible time.

  • Network Simulator NS2 is also a discrete event packet level simulator used for the simulation of wired and also wireless networks.
  • It is an open source simulation tool written in C++ and also OTCL[Object oriented extension of TCL(Tool Command language)]
  • NS2 is used to simulate Wi-Fi Networks by creating also a wireless scenario with Node standards set to  IEEE 802.11
  • Two significant components of 802.11 implementation are MAC [Medium access control] layer and also Physical layer. NS2 uses the following parameters to analyze the behavior of Wi-Fi Networks:
    • -Throughput[calculated also by measuring the bytes received by a Node]
    • -Packet drop rate[Number of packets dropped also by Sink per unit time]
    • -Average packets end to end delay[Time delay of the packets transferring from source to destination]

         To understand about how also to simulate a Wi-Fi Network in NS-2, let’s take an example program. We also have taken six Wi-Fi Nodes and 9 User equipment i.e. totally 15 Nodes in our example program. Also, We have defined the MAC address as IEEE 802.11 and used DSDV Ad-hoc routing protocol for our ease. Now, create also a TCL file named Filename.tcl and write the simulation program as following:

Define the Options in TCL script:

setval(chan)   Channel/WirelessChannel

set val(prop)   Propagation/TwoRayGround

setval(ant)    Antenna/OmniAntenna

set val(ll)     LL

setval(ifq)    Queue/DropTail/PriQueue

set val(ifqlen) 50

setval(netif)  Phy/WirelessPhy

set val(mac)    Mac/802_11// Set to Wi-Fi Network standard

set val(rp)     DSDV

setval(nn)     15

set val(x)      1000

setval(y)      1050

set val(stop)   20.5

setval(traffic)        cbr

set val(traffic)        tcp

To create an instance of the simulator:

set ns [new Simulator]

To create a Trace file and NAM file:

set tracefd       [open out.tr w]

set namtrace      [open out.nam w]

$ns trace-all $tracefd

$ns namtrace-all-wireless $namtrace $val(x) $val(y)

To set up a topography object:

set  topo [new  Topography ]

$topo load_flatgrid  $ val(x)  $ val(y)

To create the object God:

set god_ [create-god $val(nn)]

To Configure the Nodes:

$ns node-config -adhocRouting $val(rp) \

-llType $val(ll) \

-macType $val(mac) \

-ifqType $val(ifq) \

-ifqLen $val(ifqlen) \

-antType $val(ant) \

-propType $val(prop) \

-phyType $val(netif) \

-channelType $val(chan) \

-topoInstance $topo \

-agentTrace ON \

-routerTrace ON \

-macTrace OFF \

-movementTrace ON

Creation of 15 Wireless Nodes:

Create a Node object:

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

set node_($i) [$ns node]}

To define the Node Initial position in NAM:

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

$ns initial_node_pos $node_($i) 30}

To change the Node Color at time[0.2s]:

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

$node_($i) color yellow

$ns at 0.2 “$node_($i) color red”}

for {set i 6} {$i < 15} {incr i } {

$node_($i) color yellow

$ns at 0.2 “$node_($i) color dodgerblue” }

 To define the label for the Node at the time[0.2]:

for {set i 0} {$i < 6 } {incr i } {

$ns at 0.2 “$node_($i) label \”WiFi\””  }

for {set i 0} {$i < 6 } {incr i } {

$ns at 0.2 “$node_($i) label \”UE\”” }

To declare the position X,Y, Z  for the required node:

$node_(0) set X_ 25.0

$ node_(0) set Y_ 313.0

$node_(0) set Z_ 0.0

$ node_(1) set X_ 523.0

$node_(1) set Y_ 388.0

$ node_(1) set Z_ 0.0

$node_(2) set X_ 717.0

$ node_(2) set Y_ 600.0

$node_(2) set Z_ 0.0

$ node_(3) set X_ 627.0

$node_(3) set Y_ 106.0

$ node_(3) set Z_ 0.0

$node_(4) set X_ 227.0

$ node_(4) set Y_ 888.0

$node_(4) set Z_ 0.0

$ node_(5) set X_ 627.0

$node_(5) set Y_ 307.0

$ node_(5) set Z_ 0.0

set tcp [new Agent/TCP]

$tcp set class_ 1

set sink [new Agent/TCPSink]

$ns attach-agent $node_(0) $tcp

$ ns attach-agent $node_(6) $sink

$ns connect $tcp $sink

set ftp [new Application/FTP]

$ftp attach-agent $tcp

$ns at 0.500000000000 “$ftp start”

$ns at 19.500000000000 “$ftp stop”

To create a random mobility positions for UE:

proc destination {} {

global ns val node_

set time 1.0

set now [$ns now]

for {set i 6} {$i<$val(nn)} {incr i} {

set xx [expr rand()*1000]

set yy [expr rand()*800]

$ns at $now “$node_($i) setdest $xx $yy 1000.0”

}  $ns at [expr $now+$time] “destination”}

Set the simulation termination time:

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

$ns at $val(stop) “$node_($i) reset”;}

To End the simulation:

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

$ ns at $val(stop) “stop”

$ns at 21.5 “puts \”end simulation\” ; $ns halt”

proc stop {} {

global ns tracefd namtrace

$ns flush-trace

close $tracefd

close $namtrace

exec nam out.nam &}

$ns run

To run the simulation program:

$ns filename.tcl
