Contiki80211: An IEEE 802.11 Radio Link Layer for the Contiki OS

We believe that the existing 802.11 MAC layer can be optimized (especially for energy-efficiency) to make Wi-Fi suitable for a wide range of IoT applications. However, there is a lack of low-cost embedded platforms to be used for experimentation with 802.11 MAC. The majority of low-power Wi-Fi modules for embedded systems has closed source firmware and protocol stack implementations, which prevents implementation and testing of new protocol features. Here we describe Contiki80211, an open source 802.11 radio link layer implementation for Contiki OS, optimized for resource constrained embedded platforms, whose purpose is to enable experimentation with 802.11 MAC layer management mechanisms on embedded devices.
