I assume the reader is already familiar with the Mininet network emulator so I cover only the new WiFi features added by Mininet-WiFi. Once you work through the tutorials in this post, you will be well equipped to discover all the features in Mininet-WiFi by working through the Mininet-WiFi example scripts, and reading the Mininet-WiFi wiki and mailing list. I do not attempt to cover every feature in Mininet-WiFi. I suggest new users work through each tutorial in order. In this post, I present the basic functionality of Mininet-WiFi by working through a series of tutorials, each of which works through Mininet-WiFi features, while building on the knowledge presented in the previous tutorial. At the top of that page is a link to the Mininet-WiFi manual, which is currently hosted at. Please refer to the Mininet-WiFi documentation for up-to-date information about this project. Some of the information in this post may be outdated and no longer accurate. (Updated October 20, 2017) Since I wrote this post two years ago, the Mininet-WiFi developers have continued to add a lot of functionality to Mininet-WiFi. In this post, I describe the unique functions available in the Mininet-WiFi network emulator and work through a few tutorials exploring its features. So, Mininet-WiFi adds new functionality and still supports all the normal SDN emulation capabilities of the standard Mininet network emulator. The Mininet-WiFi extended the base Mininet code by adding or modifying classes and scripts. They also added classes to support the addition of these wireless devices in a Mininet network scenario and to emulate the attributes of a mobile station such as position and movement relative to the access points. The Mininet-WiFi developers extended the functionality of Mininet by adding virtualized WiFi stations and access points based on the standard Linux wireless drivers and the 80211_hwsim wireless simulation driver. In such a case, switching to Google DNS or DNS Servers provided by Amazon or Open-DNS might help in fixing the issue.įree DNS servers as provided by Google, Amazon and Open-DNS are reliable and likely to be much faster than DNS Servers used by your Internet Service Provider.Mininet-WiFi is a fork of the Mininet SDN network emulator. If you are frequently experiencing WiFi connectivity problems on your Mac, the issue might be related to DNS server of your Internet Service Provider (ISP) being crowded.
