Hello,

I'm using tinyos-2.1.1, blip stack (2.0) and default LowPowerListening.

I've about 60 motes (TelosB and IRIS) deployed around a 2 floors  
building and some of them are 5 hops from the IPBaseStation.

Not all of my motes are running on battery and those who are plugged  
on electric socket might be better routers from a power consumption  
point of view so I'm wondering if there is any way to change metrics  
forcing one mote to hop on "particular" motes. From the ip-driver  
shell, I've set one mote as "controller" but this modification doesn't  
seems to change routes or routing behavior encouraging motes to use  
the controller as first hop. am I doing it wrong?

I'm also wondering if I can have more than one sink on the same  
network in order to collect data generated by sensors in more than one  
point. As far as I know is not possible to have two ip-driver running  
or one ip-driver managing two IPBaseStation on the same network. Is it  
right?


Thanks in advance for any answer or suggestion
