[orbit-user] Having difficulty in setting up multi-hopenvironment.

[Sanjit Krishnan Kaul]

Thanks. 

 

What is the frequency setting of the noise antennas and the nodes you are
using? What bit-rates are you operating at? Can you send all your settings,
maybe the script you are using (if it is a node-handler script)?

It is difficult to understand why at 5dbm noise the link from [6,6] to [2,2]
is not seeing packet errors as [2,2] is adjacent to a noise-antenna.

 

Cheers,

Sanjit

The noise antenna power I tried are -20dBm, -10dBm, 0dBm, and 5dBm. The code
to set nodes' antenna power seems does not work. So the antenna power of
nodes is 20dBm.

Grid nodes are [[2,2],[6,6]].

I want to make the forwarding probability between these two nodes less than
30%.

What noise antenna power did u use? What orbit grid nodes did u select? What
number of hops are you looking for?

Hi,

 

I have difficulty in configuring multi-hop environment by injecting noise. I
tried the sample codes and changed some parameters, such as antenna power
and radio power. But the forwarding probabilities were always >99%. Is there
anyone has configured a similar environment? Could you share the code?
Thanks a lot! 

 

By the way, the code I used for setting radio power seems not right. Anyone
has any idea?

allGroups.net.w0 { |w|

  w.power = "18dBm"

}

 

Thanks a lot!
