A Review of Dew and Edge Computing: Two Sides of a Modern Internet of Things Solution

Dew and edge computing are the sophisticated post-cloud architectural approaches that bring computing closer to the user for applications addressing the Internet of Things. In this paper, we analyze the requirements of post-cloud architectures to build such a solution, which clarify the main differences between dew and edge computing approaches. The analysis includes energy consumption, communication and processing requirements, latency, and throughput, and the evaluation shows how these requirements impact performance. In addition, we also analyze architectural approaches, including hardware/software coexistence, scalability, hardwareless computing, virtualization, interoperability, and portability. This research will check the validity of a hypothesis whether the dew and edge computing two sides of the same modern Internet of Things solution.
