hello,
sorry to be a bother again. i solved all the previous problems mentioned
earlier.BUT i have a final problem on my simulation. i configured my mobile
node to move from bs1 to bs2 to bs3 to bs4 BUT it doesnt move. i have tried all
i can but no luck.please does any one know what could be wrong.below is my
script.
