An Overview SETDEST tool for NS-2
SETDEST tool- SETDEST tool is used for setting nodes’ mobility, pause time area under which node will move, and finally you will get rid of manually setting of nodes axes X, Y and Z and mobility.
The syntax of the set dest is
setdest -v <2> -n <nodes> -s <speed type> -m <min speed> -M <max speed>
-t <simulation time> -P <pause type> -p <pause time> -x <max X> -y <max Y>
Example
setdest -v 2 -n 10 -s 2 -m 1 -M 3 -t 100 -P 1 -p 2 -x 400 -y 500 > nodes-10
this will produce the following result in nodes-10 file .
include it adding this line
source nodes-10
in ns-2 tcl file
for {set i 0} {$i < $opt(nn)} {incr i} {
set node_($i) [$ns_ node]
}
source nodes-10
for {set i 0} {$i < $opt(nn)} {incr i} {
$ns_ initial_node_pos $node_($i) 20
}
