[orbit-user] A problem on noise injection

[Fan Wu]

Hi,

 

I am trying to inject noise into the grid. But I always get errors on this.
My code for noise injection is as follows:

 

defGroup('commander', [2,2])

defGroup('worker', [6,6])

         

allGroups.net.w0 { |w|

  w.mode = "ad-hoc"

  w.type = 'b'

  w.channel = "2"

  w.essid = "opp"

  w.rate = "11M"

  w.tx_power = "18dBm"

  w.ip = "%192.168.%x.%y"

}

 

antenna(4,4).signal {|s|

  s.bandwidth = 10

  s.channel = 2

  s.power = -10

}

 

whenAllUp() {|node|

         wait 30

         antenna(4,4).signal.on

         wait 30

         Experiment.done

}

 

The error message is like this:

 

INFO init: NodeHandler Version 4.2.0 (1272)

 INFO init: Experiment ID: grid_2008_02_19_03_53_37

 INFO Experiment: load system:exp:stdlib

&bandwidth=10)

The script runs smoothly without noise injection part. Does anyone know how
to solve this problem?

 

Thanks a lot!
