hi Mohammad,
It seems that you have mixed things up,,,,,,,but no rush,,,,,,,actually, in
wireless networks you DO NOT need to set up any links between wireless nodes
as you have done in your script when you set a duplex link between node0 and
node2,,,,,,,,,Also, for this simple scenario I don't know why you have used
hierarchical addressing instead of flat addressing???,,,,,,,the property
wiredRoutin ON, is used in wireless-cum-wired type of networks, you don't
have to use it here,,,,just remove it,,,,you need simply review your script
and check those scripts in marc's tutorial,,,,,,
hope this will help,,,,,,,,,
Note: I marked the line which you need to change in your script,,,,,,,,,just
have a look at them,,,,,,,,,,,,,
