Query: Learning Wi-Fi Connection Loss Predictions for Seamless Vertical
  Handovers Using Multipath TCP   We present a novel data-driven approach to perform smooth Wi-Fi/cellular
handovers on smartphones. Our approach relies on data provided by multiple
smartphone sensors (e.g., Wi-Fi RSSI, acceleration, compass, step counter, air
pressure) to predict Wi-Fi connection loss and uses Multipath TCP to
dynamically switch between different connectivity modes. We train a random
forest classifier and an artificial neural network on real-world sensor data
collected by five smartphone users over a period of three months. The trained
models are executed on smartphones to reliably predict Wi-Fi connection loss 15
seconds ahead of time, with a precision of up to 0.97 and a recall of up to
0.98. Furthermore, we present results for four DASH video streaming experiments
that run on a Nexus 5 smartphone using available Wi-Fi/cellular networks. The
neural network predictions for Wi-Fi connection loss are used to establish
MPTCP subflows on the cellular link. The experiments show that our approach
provides seamless wireless connectivity, improves quality of experience of DASH
video streaming, and requires less cellular data compared to handover
approaches without Wi-Fi connection loss predictions.
