Pashinin (Institute for System Dynamics and Control Theory of SB RAS, Irkutsk, Russian Federation) Microservice Approach to the Qualitative Study of Attractors of Binary Dynamic Systems Based on the Boolean Constraint Method  In recent years, due to the active development of distributed computing technologies, the automation of computations based on these technologies became very important for solving the problems of qualitative research of binary dynamic systems, which are widely used as mathematical models in cryptography, bioinformatics, the study of fault tolerance of computer networks, and some other domains. In this regard, the issues of developing tools and providing infrastructures for the conversion of scientific applications to service-oriented ones, which are characterized by the dynamism of resource requirements, including applications oriented to use in a hybrid cloud environment, are actualized. We offer microservice-oriented automation tools for managing hybrid computations for solving complex problems for a qualitative study (based on the Boolean constraint method) of attractors of binary dynamic systems to find the evolutionary parameters of system states ( for example, radius, period, and branching) without simulation. These tools provide the agents implemented as web-services for the integration of resources of on-premises computers with cloud resources using Dew computing. An example of the application of the developed tools is given. 2. M. Gusev (University Sts Cyril and Methodius, Skopje, Macedonia) Impact of Dew Computing on Cyber-Physical Systems and IoT  Cyber-physical systems and IoT devices are part of today’s interconnected networked world and participate in huge data exchange transfer. Owners of related devices and systems tend to use them independently of external systems and in addition, to be autonomous devices and systems that can perform their tasks without any external support. Edge computing refers to devices on the edge of the Internet, as they integrate into a more complex cyber-physical system. The concept of edge computing means that the corresponding cloud and edge servers are always connected to the edge devices and IoT. In the analyzed case, although these devices and systems can work in an integrated environment, they are rather classified into the dew computing concept, giving them an environment for autonomous performance, independent of surrounding devices and systems. This paper elaborates the underlying concept, benefits, market trends and impact of integrating the dew computing concept to the cyber-physical systems and IoT devices. 3. Z. Šojat, K. Skala (Institut Ruđer Bošković, Zagreb, Croatia) The Rainbow through the Lens of Dew  Ecological Responsibility of Computer Science is essential in further development of the science and application of computer technology. The rapid development of all kinds of computer controlled things and mobile devices, without and with Internet connectivity, represents presently the most prominent information technology application area. On the lowest level, below the Edge of Internet, we have a huge amount of individual devices (“things”) which do actually the most significant amount of information processing. Those are computer controlled utensils of all kinds – cars, boilers, production machines, traffic lights, plant carers etc., directly intertwined with our natural and human physical environment and our immediate surroundings. These devices, which are neither at the Cloud or Fog edge, nor even at the mobile edge, are the basis of the Dew Computing Paradigm. Further exploration and usage of the realm of possibilities of Dew Computing will solve the basic problems of integration of the "dew" level with the higher service level(s) in the Dew-Fog-Cloud hierarchy. When the distributed Cloud-Dew service architecture is developed and adopted, a Cloud server and many Dew servers will be able to cooperate as a distributed application to provide controls or services. In view of that it is absolutely necessary to see the present (and specifically future) development through the eyes of Philosophy of Computing and Ethics, and further the development through application of Ethical and Ecological principles. The Rainbow Ecosystem is a pragmatical hierarchical abstract cybernetic representation of an ecologically viable system, consisting of 9 essential areas, and applicable recursively throughout the integrated hierarchy. The ecological viability of the abstract system will enable proper ecologically responsible development of Rainbow Computing Services, integrating our living Nature-Human-Machine ecosystem. 4. Y. Wang (University of Prince Edward Island, Charlottetown, PE, Canada) A Disaster-Resilient Messaging Protocol Based on Dew Computing  Communication is vitally important during disasters. This paper proposes a new messaging protocol that is resilient to a limited or destroyed network environment based on the principles of dew computing. The goal of this messaging protocol is to make messengers adapt to both normal environment and disastrous environment. In normal environment, client-server architecture provides efficient communication; in disastrous environment, the messengers will make full use of all possible communication links automatically so that vital information can be transmitted whenever it is possible. 5.

Wang (University of Prince Edward Island, Charlottetown, Canada) Ensuring Resource Availability with MRU/FRU Caching: A Dew-Blockcloud Model  Combining the blockchain and cloud computing systems in different ways in order to address computing issues such as decentralization and security has slowly become a norm in recent times. These Block-Cloud model(s), which are becoming prominent in the literature seem to ensure integrity in the Cloud but lacks in exhibiting availability of resources, which is essential for security. In this study, a dew-blockcloud model is designed to address this problem. We propose a hybrid MRU/FRU caching algorithm for the dew server that reduces the number of repeated cloud accesses while maintaining relevant updated data.Using existing literature and postulation we show that dew computing might be the best availability system for the blockcloud model. 6.

Essuman (Ghana Technonology University College, Accra, Ghana) The Relevance of Blockchain with Dew Computing: a Review  Blockchain after its discovery and application to bitcoin has become a vital platform for data validation and verification across diverse sectors such as healthcare, supply chain, governance, and many others. The era of cloud computing has facilitated the access of one’s data on the go making it almost impossible to lose data as your work. However, the use of the cloud demands constant aces to the internet warranting the relevance of the dew computing paradigm with terms to give access to one’s data locally without the use of the internet and then updating the document on the cloud based on the internet restoration. In this paper, we seek to conduct a review of the above areas of blockchain and dew computing drawing the need for the integration of both technologies.

An Open Forum discussion on the IEEE DewCom STC program to launch various development and collaborative program and project initiatives will be a part of this special session.
