- Abstract
The dew computing paradigm is emerging as a complement of cloud computing to cover its limitations. Independence is one of the essential features of dew computing. It means that it can continue to provide services without an Internet connection. These characteristics of dew computing allow it to find a niche in real-time applications. The importance of real-time applications in daily human life is not hidden due to the growing development of the Internet of Things. In this paper, the hierarchical architecture of cloud-fog-dew is presented to overcome the limitations of cloud computing in real-time applications such as latency and resource management. Also, a Mixed Integer Non-Linear Programming model is presented for the scheduling of real-time applications in the proposed architecture. It aims to reduce power consumption and Internet traffic. Besides, the proposed model is supported by Non-dominated Sorting Genetic Algorithm II to provide scalability. The simulation results demonstrate that completing tasks in the dew computing layer can reduce Internet dependency while also reducing power consumption and traffic. As a result, under the suggested paradigm, the number of tasks missed due to stoppage or Internet disturbance is reduced.
