We have set up a testbed of 4 programmable TP-LINK WDR3500 wireless routers
running customized OpenWRT firmware, which we experiment with joint channel
assignment, rate adaption and client association algorithms. On device side, we
hacked \wifi{} driver of Nexus 5 devices to enable \wifi{} monitor mode. This
enables the device to ``sniff'' the detailed spectrum utilization information.
We are currently developing an \PS{} Android app. Besides sniffing, the app will
also collect and upload network measurements such as \wifi{} scan results, RTT
of \texttt{ping} requests, bandwidth etc. We plan to deploy our app on
\PhoneLab{}, a large smartphone testbed operated at UB.
