| 83 | - More and more wireless devices are competing for the limited spectrum | ||
| 84 | - resources. Recent studies have shown the value of client-side measurements | ||
| 85 | - in determining better channel assignment. Yet \textbf{how to collect data | ||
| 86 | - from clients without interrupting their normal usage} remains to be an | ||
| 87 | - open question. To address this problem, we propose \PS{}---\textbf{a | ||
| 88 | - framework for client-side measurements collection}. The key idea is to | ||
| 89 | - \textbf{use inactive smartphones to perform measurements on behalf of | ||
| 90 | - nearby devices} to improve spectrum allocation. \PS{} also collects the | ||
| 91 | - network measurements naturally generated by smartphones to monitor the | ||
| 92 | - health and performance of large-scale wireless networks. | ||

| 206 | - We hacked the driver of Nexus 5 smartphones to support Wifi monitor | ||
| 207 | - mode. We also set up several TP-LINK WDR3500 wireless routers running | ||
| 208 | - OpenWRT as \PS{} APs. We conducted a simple channel adaptation experiment as | ||
| 209 | - follows: | ||
| 210 | - \begin{enumerate} | ||
| 211 | - \item \textbf{0--7~s}\quad TCP link between \PS{} AP and device $A$. | ||
| 212 | - \item \textbf{7--75~s}\quad $B$ jams the channel, causing bandwidth | ||
| 213 | - degradation and jitter of $A$. | ||
| 214 | - \item \textbf{75--100~s}\quad AP switches to a less congested channel with | ||
| 215 | - the help of nearby device $C$. | ||
| 216 | - \end{enumerate} | ||
| 217 | - Throughout the experiment, \textbf{device $A$'s active session is not | ||
| 218 | - affected---neither $A$'s association with AP or TCP link is interrupted by | ||
| 219 | - the channel switch}. | ||
| 220 | - | ||
| 221 | - This experiment demonstrate the feasibility of \PS{} in single SP, managed | ||
| 222 | - clients scenario. We're extending the system to other three scenarios. | ||
