[ns] gridkeeper

[Oluseye O Ojumu <tmfcello@MIT.EDU>]

hi all;

can anyone tell me what a gridkeeper is??
i found it in a couple of scripts ( tcl/ex/grid2.tcl , 
tcl/ex/gridkeeper.tcl ). alternatively, could someone
tell me  about the radius option for nodes; it doesn't
seem to work. i saw in one of the tcl scripts that 
radius only works with grid which brings us back to that
problem. 

kind of related, is there a way to set the radius in units
of distance that a mobile node can broadcast; the 
$mobilenode radius <radius> command claims to be able to 
do it, but it doesn't seem to quite work.

any help is appreciated; thank you.

seye
