Open questions on the effectiveness and longevity of fog, edge, and cloud infrastructures

Investigate the long‑term effectiveness, energy efficiency, and sustainability of fog, edge, and cloud infrastructures, including data encoding, scheduling, thermal management, and energy harvesting strategies that improve durability and reduce power consumption without sacrificing QoS.

Background

The paper observes rapidly growing data volumes and device counts, pushing fog/edge/cloud systems to address energy efficiency and sustainability while preserving QoS.

It explicitly flags that many questions about effectiveness and longevity remain, pointing to research needs in encoding, thermal modeling, scheduling, and energy harvesting.
