I have done research on WiFi and IEEE802.15.4 interference. I proposed a method to mitigate interference by using a time-slot way. In order to schedule the WiFi traffic, CTS frames can be injected to suppress ongoing WiFi traffic for a period of up to 32 milliseconds. However, this wouldn’t work by using a normal Linux kernel. I achieved this by modifying the ath9k driver of AR9331 on Openwrt.
please use it for research purpose only and contact me for the detail.
