How to configure nodes in ns2?
  • Each node in the network can be configured as follows
  • # Defining Optionsset rp AODV;# routing protocolset llLL;# link layer typeset macMac/802_11;# MAC typeset ifqQueue/DropTail/PriQueue;# interface queue typeset ifqlen50;# max packet in ifqset antAntenna/OmniAntenna;# antenna model

    set propPropagation/TwoRayGround; # radio-propagation model

    set netifPhy/WirelessPhy; # network interface type

    set chanChannel/WirelessChannel; # channel type

    set val(x)1000; # X dimension of topography

    set val(y)1000; # Y dimension of topography

    set topo [new Topography]

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

    set ns [new Simulator] ; # Simulator instance

    # Creating nodes with this Configuration
