How to Run Mininet-Wifi?

Step by Step Run Mininet-Wifi


      Mininet-WiFi is free software to emulate wireless OpenFlow/SDN scenarios allowing high-fidelity experiments that replicate real networking ambiance. Mininet-WiFi is a diverging part of the Mininet SDN network simulator, which expands the functionality of Mininet ( that allows the use of both WiFi Stations and Access Points. Mininet-WiFi only adds wifi features and works like users were working with Mininet. While using Mininet-Wifi, users can use any wireless network tools (iw, iwconfig, wpa_supplicant). To work and Run with Mininet-Wifi, the user should follow the rules and procedure listed below.

       Start a minimal topology and enter the CLI:

       $ sudo mn --wifi

       The default topology is the minimal topology, which includes one OpenFlow kernel AP connected to two stations plus the OpenFlow reference controller.

      This topology could also be specified on the command line with –topo=minimal. Other topologies are also available out of the box; see the –topo section in the output of mn -h.

      All four entities (2 stations processes, one ap process, and one basic controller) are now running.

       Display Nodes:

      mininet-wifi> nodes

      The command is executed on that node if the first string typed into the Mininet-WiFi CLI is a station, ap, or controller name. Run a command on a station process:

      You should see the station’s sta-wlan0 and loopback (lo) interfaces. Note that this interface (sta1-wlan0) is not seen by the primary Linux system when ifconfig is run because it is specific to the network namespace of the host process.

      In contrast, the ap by default runs in the root network namespace, so running a command on the ap is the same as running it from a regular terminal:

      mininet-wifi> ap1 ifconfig -a

      Getting information from the node.params

       py sta1.params

      Getting information on the wireless network interfaces

      py sta1.wintfs

      Optionally, you can get some other information about the interface

      py sta1.wintfs[0].txpower

      The same can be done for rssi, mode, channel, freq, range, ip, ip6, etc.
