Preserving privacy in sensor-fog networks

To address the privacy-utility tradeoff associated with wireless sensor networks in general, and a smart television remote in particular, we study and test usability factors and privacy aspects associated with the current framework models of a TV remote, and port the paradigm of Fog computing to arrive at an optimal solution. A Fog node, being closer to the end-devices not only mitigates the problem of latency but also enables computationally expensive operations, which were earlier possible only at cloud-side. We explore various adversary models, which can potentially compromise our framework and suggest measures to help avoid them.
