propagation models #95

Closed akhila-rao closed 7 years ago

akhila-rao commented 8 years ago

Hi,

I would like to use (and modify) the propagation model used for the wifi links in OpenNet. From what I have gathered, the ns3.py file has the function definitions to access ns3 classes. I see that functions to access mobility related classes have been defined in ns3.py. I, however, could not find anything to set or modify the propagation model in this ns3.py file. I hence added some functionality into the ns3.py file for this purpose. How do I now bind these changes to OpenNet. I suppose I need to do some kind of build to add these changes into the byte code. How do I do this ?

Thank you.

OpenNet uses NS-3 to model the propagation media, while NS-3 uses channel to represent propagation media. In ns3.py, you can find that the script uses ns.wifi.YansWifiChannelHelper to create the Wi-Fi channel.

After you made modification on ns3.py, just run "./install.sh -n" under mininet/util to build mininet.

By the way, Piotr Jurkiewicz owns the original credit of ns3.py. Most of methods and classed are created by Piotr Jurkiewicz, except WifiSegment, which is implemented by OpenNet.
