How to Install WIRELESS PHY.H Packages in Ns2

To import Wireless-phy.h packages in NS2. Get research ideas and detailed guidance from ns2projects.com team. The WirelessPhy.h file is integral to the simulation of the physical layer within wireless networks. It effectively models the behavior of the wireless medium, encompassing the transmission and reception of data packets. This component interacts with upper layers, such as the MAC layer, to manage radio transmission attributes, including signal strength, noise, and interference, which are essential for accurately replicating wireless communication scenarios. The WirelessPhy.h file includes declarations for various methods and variables pertinent to the wireless physical layer, such as determining the maximum distance a signal can cover and the minimum power level required for a node to successfully receive a signal. Additionally, it aids in simulating real-world conditions, including free-space and two-ray ground reflection models, as well as interference and noise models that replicate the impact of background noise and interference from other signals.

Steps that are required for the installation of Wireless-phy.h.

PRE-REQUISITES:

Fresh installation of Ubuntu 16.04 LTS:

HEADER FILE VERIFICATION:

Locate to the ns-2.35 folder:

2.Create the Main.tcl file in the scratch folder:

Next we need to create the Main.tcl file by using text editor in the ns-2.35 folder.

Screenshot:

Next we need to paste the below code to the Main.tcl file and save the file in the ns-2.35 folder.

Code:

set val(chan) Channel/WirelessChannel

set val(prop) Propagation/TwoRayGround

set val(netif) Phy/WirelessPhy

set val(mac) Mac/Simple

set val(ifq) Queue/DropTail/PriQueue

set val(ll) LL

set val(ant) Antenna/OmniAntenna

set val(ifqlen) 50

set val(nn) 2

set val(rp) DumbAgent

set val(x) 250

set val(y) 250

set ns_ [new Simulator]

set tracefd [open wireless-simple-mac.tr w]

$ns_ trace-all $tracefd

set namtrace [open wireless-simple-mac.nam w]

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

set topo [new Topography]

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

create-god $val(nn)

set chan_ [new $val(chan)]

$ns_ initial_node_pos $node_($i) 20}

$node_(0) set X_ 15.0

$node_(0) set Y_ 15.0

$node_(0) set Z_ 0.0

$node_(1) set X_ 150.0

$node_(1) set Y_ 150.0

$node_(1) set Z_ 0.0

$ns_ at 3.0 “$node_(1) setdest 240.0 240.0 30.0”

set tcp [new Agent/TCP]

$tcp set class_ 2

set sink [new Agent/TCPSink]

$ns_ attach-agent $node_(1) $sink

$ns_ connect $tcp $sink

set ftp [new Application/FTP]

$ftp attach-agent $tcp

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

$ns_ at 6.0 “$node_($i) reset”;}

proc stop {} {

global ns_ tracefd namtrace

$ns_ flush-trace

close $tracefd

close $namtrace

exec nam wireless-simple-mac.nam &

exit 0}

$ns_ at 6.0 “stop”

$ns_ at 6.01 “puts \”NS EXITING…\” ; $ns_ halt”

$ns_ run

Screenshot:

Open the Terminal:

Next, we need to launch the terminal by right clicking the mouse in the ns-2.35 location.

3.NS-2.35 Configuration && Building Process:

Next, we need to configure and build the ns-2.35 folder to make the Created files need to work in ns-2.35 configuration.

Command: “./make”

Screenshot:

Here, NS-2.35 Building process completed successfully.

3.Importing Wireless-phy.h:

Here we imported the Wireless-phy.h header file code indirectly accessed the Telnet class used in the Tcl script (set val(netif) Phy/WirelessPhy) are used for simulating the physical layer in wireless networks. This configuration helps to create Wireless Medium in the network in this example program. Here we highlighted the code line that highlighted which is internally accessed Wireless-phy.h, we will show class file that used in this code via Mac folder.

Screenshot:

Here we will show the header file by opening Wireless-phy.h file to show the class or function imported from the Wireless-phy.h in the example code. This Tcl Script Line (set val(netif) Phy/WirelessPhy) are used for simulating the physical layer in wireless networks. This configuration helps to create Wireless Medium for Each Nodes in the network in this example program.

4.Executing the Example Program for Wireless-phy Header:

Then we need to run the Example program for Wireless-phy Header to view output of the program.

Command: “./ns Main.tcl”

Screenshot:

Here we shown the output of the example program by using Wireless-phy.h.

Screenshot:

In the NS 2.35 Simulation Example Program, the Wireless-phy.h Header file is successfully imported.
