What makes Dew computing more than Edge computing for Internet of Things

A lot of research and development activities have been referencing to edge and dew computing solutions for IoT applications, but without determining the deep distinction between these two architectural approaches. Furthermore, there is no clear explanation if dew computing is a special case of edge computing or the opposite. In this paper, we analyze the features of post-cloud architectures to build an IoT solution and clarify the main differences between dew and edge computing approaches. Although the provided analysis covers IoT solutions, still the same principles can be applied more generally.
