NS2/SUMO

$] netconvert --osm-files guindy.osm -o guindy.net.xml

Now, copy the osmPolyconvert.typ.xml from the $SUMO_HOME/data/typemap/ and copy it to the folder where you put all the files.*

$] polyconvert --osm-files*guindy.osm*--net-file*guindy.net.xml --type-file osmPolyconvert.typ.xml -o*guindy.poly.xml

$] python $SUMO_HOME/tools/randomTrips.

Now, create a new file (to be named as guindy.sumo.cfg) and paste the following lines*

*<configuration>
* * *<input>
* * * * *<net-file value="guindy.net.xml"/>
<route-files value="guindy.rou.xml"/>
* * * * *<additional-files value="guindy.poly.xml"/>
* * *</input>
<time>
<begin value="0"/>
<end value="100"/>
<step-length value="0.1"/>
</time>
*</configuration>

Step 3: Exporting to NS2
from sumo trace to ns2, here is the step to do
Open terminal and type the following commands,
$] sumo -c guindy.sumo.cfg --fcd-output guindy.sumo.xml

$] python3 /home/pradeepkumar/sumo-0.26.

This will generate three tcl files (guindy.tcl, activity.tcl and mobility.tcl). Among this activity.tcl might not be needed, but mobility.tcl file is mandatory)

here i replace the guindy with ect and get all these files
activity.tcl
ect.nam
ect.net.xml
ect.osm
ect.poly.xml
ect.rou.xml
ect.sumo.cfg
ect.sumo.xml
ect.tcl
ect.tr
mobility.tcl
osmPolyconvert.typ.xml
test.nam
test.tcl
test.tr
trips.trips.xml

and i get this error

maisha@maisha-ASUS:~/ect$ ns ect.tcl
