Hereby, our technical professionals have highlighted the languages which are used to create the network scenario file through the execution of network simulator 2.

• OTcl
• C++

Creation of Network Scenario File by Ns2

We are capable to create the network scenario file through the utilization of language namely OTcl / Tcl in network simulator 2. The sample code to create network scenario file is highlighted in the following.

• Ns2 code to specify node position randomly

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

     set xx [expr {int(rand()*$val(x))}]

     set yy [expr {int(rand()*$val(y))}]

     $node_($i) set X_ $xx

     $node_($i) set Y_ $yy

     set nodeXpos($i) $xx

     set nodeYpos($i) $yy

     set nodeZpos($i) 0.0                          

}

• Ns2 code to create trace file objects and network topography

$ns trace-all $tracefd

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

set topo [new Topography]

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

• Ns2 code to initialize the network configuration

set val(chan)               Channel/WirelessChannel

set val(prop)               Propagation/TwoRayGround

set val(ant)      Antenna/OmniAntenna

set val(ifq)      Queue/DropTail/PriQueue

set val(ifqlen)             50

set val(netif)  Phy/WirelessPhy

set val(mac)                Mac/802_11
