1st International Workshop on Smart Computing
for Industrial and Real-World Systems
Welcome from the Program Co-Chairs
It is our great pleasure to welcome you to the 1st IEEE International Workshop on Smart Computing for Industrial and Real-World Systems (SCIRS 2020) co-located with the 6th IEEE International Conference on Smart Computing (SMARTCOMP 2020) held on September 2020. The spread of the Internet of Things (IoT) in industrial environments has fostered the development of new Industrial IoT (IIoT) applications and, more in general, the advent of the Industry 4.0 revolution. The current trend is towards the development of connected machines
able to interact with each other as well as to send data and access cloud and Internet services.
Smart components and services within industrial environments represent a novel and promising solution not only to better support QoS requirements, but also to more easily reconcile safety requirements of Operational Technology with the openness and dynamicity typical of the Information Technology. Moreover, the emergence of edge devices equipped with relatively high computational, memory, and storage capabilities facilitates the adoption of these technologies. They are not only able to increase the efficiency of existing industrial processes, e.g., by more promptly identifying faulty machines to reduce the downtime and maximize OLE/OEE KPIs, but
also to provide new business opportunities, e.g., by widening the market through the provision of industrial equipment based on pay-per-use fees. The objective of the SCIRS 2020 workshop is to provide a forum to exchange ideas, share experience, and enhance collaborations in various aspects of smart computing in industrial
environments, by focusing on real-world use cases and applications.
We thank all the authors for submitting their work. We are grateful to the TPC members for their hard work in reviewing the papers. We hope you enjoy this workshop. Thank you for your participation

Strongly stable bases for adaptively refined multilevel spline spaces
No full textThe problem of constructing a normalized hierarchical basis for adaptively refined spline spaces is addressed. Multilevel representations are defined in terms of a hierarchy of basis functions, reflecting different levels of refinement. When the hierarchical model is constructed by considering an underlying sequence of bases Γℓ=0,…,N−1 with properties analogous to classical tensor-product B-splines, we can define a set of locally supported basis functions that form a partition of unity and possess the property of coefficient preservation, i.e., they preserve the coefficients of functions represented with respect to one of the bases Γℓ. Our construction relies on a certain truncation procedure, which eliminates the contributions of functions from finer levels in the hierarchy to coarser level ones. Consequently, the support of the original basis functions defined on coarse grids is possibly reduced according to finer levels in the hierarchy. This truncation mechanism not only decreases the overlapping of basis supports, but it also guarantees strong stability of the construction. In addition to presenting the theory for the general framework, we apply it to hierarchically refined tensor-product spline spaces, under certain reasonable assumptions on the given knot configuration
THB-splines: The truncated basis for hierarchical splines
Full text linkThe construction of classical hierarchical B-splines can be suitably modified in order to define locally supported basis functions that form a partition of unity. We will show that this property can be obtained by reducing the support of basis functions defined on coarse grids, according to finer levels in the hierarchy of splines. This truncation not only decreases the overlapping of supports related to basis functions arising from different hierarchical levels, but it also improves the numerical properties of the corresponding hierarchical basis which is denoted as truncated hierarchical B-spline (THB-spline) basis. Several computed examples will illustrate the adaptive approximation behavior obtained by using a refinement algorithm based on THB-splines
Software-Defined Networking in wireless ad hoc scenarios: Objectives and control architectures
No full textWhile SDN has traditionally targeted fixed and wired environments with hundreds of nodes, recently its main principles have also been followed in wireless ad hoc scenarios. However, node mobility and heterogeneity characterizing such dynamic scenarios prevent the adoption of purely centralized control solutions, pushing for more articulated and distributed architectures. We provide a thorough analysis of state-of-the-art literature related to the adoption of SDN in wireless ad hoc scenarios, ranging from WSNs with mostly fixed sensors and WMNs with mobile clients but stable routers to MANETs with every node freely moving on the field, VANETs with vehicles speeding through the network road, and FANETs with aerial vehicles flying in every direction. For each identified wireless ad hoc scenario, we present the rationale behind the adoption of SDN, recognizing that the objective of the SDN controller is far beyond mere routing management in such challenging scenarios. Furthermore, we detail the proposed control architectures, showing how the peculiar characteristics (and related goals) of a given scenario influence the architecture design. Finally, we point out hybrid control architectures as a notable trend in SDN solutions targeting wireless ad hoc scenarios
Joint Orchestration of Content-Based Message Management and Traffic Flow Steering in Industrial Backbones
No full textThe industrial internet of things has radically modified industrial environments, not only enabling novel services but also dramatically increasing the amount of generated traffic. Nowadays, a major concern within industrial plants is to support network-intensive services, such as real-time remote vibration monitoring of autonomous guided vehicles, while ensuring the prompt and reliable delivery of mission-critical safety-related messages among machines and the control room. To this purpose, we present a novel solution jointly orchestrating content-based message management and traffic flow steering: the former enables edge-powered in-network processing modules to process packet payloads as they traverse the industrial backbone, the latter supports dynamic (re)routing of traffic flows towards such processing modules. In particular, we exploit software-defined networking for flexible traffic flow (re)routing and Kubernetes for dynamic deployment on edge nodes of in-network processing modules for content-based message management. As demonstrated by performance results based on our working proof-of-concept prototype, our solution efficiently allows to manage industrial traffic flows in a coordinated fashion, by considering requirements of concurrently running industrial applications and the current state of the overall topology
Edge-Powered In-Network Processing for Content-Based Message Management in Software-Defined Industrial Networks
No full textTraditional industrial networks were characterized by flat topologies, where industrial equipment exchanged a limited number of messages. In sharp contrast, modern manufacturing plants are evolving towards articulated environments generating an ever-increasing amount of network traffic. Such emerging environments prevent the adoption of traditional solutions based on end-to-end dispatching of few messages in reliable networks with bandwidth availability much greater than needed. This leads to the need to adopt proper message management strategies as close as possible to industrial equipment to avoid overwhelming the industrial network with non-mission-critical traffic at the expense of mission-critical one. This paper originally proposes edge-powered in-network processing to i) transparently manage messages sent by industrial equipment, ii) support a broad spectrum of message management strategies, ranging from efficient header-based solutions to expressive content-based ones, and iii) fulfill the application-dependent requirements demanded by industrial environments nowadays. Achieved performance results based on a proof-of-concept prototype demonstrate that the proposed solution efficiently provides content-based message management at the edge, even considering edge nodes with limited hardware capabilities
