Hello, I found this string in NS Manual, how can I use it? [quote]$mobilenode radius <r>
The radius <r> denotes the node's range. All mobilenodes that fall within the circle of radius <r> with the node at its center are considered as neighbours.[/quote] I used it like: $node_(0) radius 50 but It seems to do not work. Sorry for my poor english. thank you Andrea.
