hi all,
i am trying to send packets from one mobile node in domain 1t o sink node in
domain 2... but i get route to base station not found error...
this is the code ....

applications

and one more thing.. what is this wiredRouting in node-config... for mobile
nodes if i make the wiredRouting OFF... it gives me an error saying that
mobiles nodes have not be defined...
anyone plz help.. its urgent for my project...
thanks all
