Hi there

I am working on some code which discovers other nodes, in fact all nodes 
discover what is around them. It is possible that some nodes are hidden, that 
is they hear from others but can't communicate back. All of this is in the 
TOSSIM environment.

Is it possible, that when a Node determines that another node is a hidden / 
asymmetric node, it can tell said node to increase its radio transmit radius 
and so, potentially, bring it out of its hidden status? From reading through 
the tutorials and looking at code I realise you could do this by changing the 
gain relationship between the two, or more, nodes, which would have to 
completed at the Python level. However I can't see how a nodes transmit radius 
can be increased, is there a command to complete this?

Also, a second question, if I may, is it possible to ascertain the x / y 
co-ordinates of a node in a topology?

Thank you.

Anthony
