# configure the nodes
$ns node-config – propType $val(prop) \
# Node Creation
set node1 [$ns node]

#Propagation Model 2: TwoRayGround

set val(prop) Propagation/TwoRayGround ;# radio-propagation model
# configure the nodes
$ns node-config – propType $val(prop) \
# Node Creation
set node1 [$ns node][$ns node]

#Propagation Model 3: Shadowing

set val(prop) Propagation/ Shadowing ;# radio-propagation model
# configure the nodes
$ns node-config – propType $val(prop) \
# Node Creation
