- Adaptive offloading for infotainment systemsPublication . Ferreira, Luís Lino; Pinho, Luís Miguel; Albano, Michele; Teixeira, CésarInfotainment applications in vehicles are currently supported both by the in-vehicle platform, as well as by user’s smart devices, such as smartphones and tablets. More and more the user expects that there is a continuous service of applications inside or outside of the vehicle, provided in any of these devices (a simple but common example is hands-free mobile phone calls provided by the vehicle platform). With the increasing complexity of ‘apps’, it is necessary to support increasing levels of Quality of Service (QoS), with varying resource requirements. Users may want to start listening to music in the smartphone, or video in the tablet, being this application transparently ‘moved’ into the vehicle when it is started. This paper presents an adaptable offloading mechanism, following a service-oriented architecture pattern, which takes into account the QoS requirements of the applications being executed when making decisions.
- Advanced sensor-based maintenance in real-world exemplary casesPublication . Albano, Michele; Lino Ferreira, Luis; Orio, Giovanni Di; Maló, Pedro; Webers, Godfried; Jantunen, Erkki; Gabilondo, Iosu; Viguera, Mikel; Papa, GregorCollecting complex information on the status of machinery is the enabler for advanced maintenance activities, and one of the main players in this process is the sensor. This paper describes modern maintenance strategies that lead to Condition-Based Maintenance. This paper discusses the sensors that can be used to support maintenance, as of different categories, spanning from common off-the-shelf sensors, to specialized sensors monitoring very specific characteristics, and to virtual sensors. This paper also presents four different real-world examples of project pilots that make use of the described sensors and draws a comparison between them. In particular, each scenario has unique characteristics requiring different families of sensors, but on the other hand provides similar characteristics on other aspects.
- An Energy Flexibility Framework on The Internet of ThingsPublication . Le Guilly, Thibaut; Siksnys, Laurynas; Albano, Michele; Pedersen, Per; Stluka, Petr; Lino Ferreira, Luis; Skou, Arne; Pedersen, Torben; Olsen, PeturThis paper presents a framework for management of flexible energy loads in the context of the Internet of Things and the Smart Grid. The framework takes place in the European project Arrowhead, and aims at taking advantage of the flexibility (in time and power) of energy production and consumption offered by sets of devices, appliances or buildings, to help at solving the issue of fluctuating energy production of renewable energies. The underlying concepts are explained, the actors involved in the framework, their incentives and interactions are detailed, and a technical overview is provided. An implementation of the framework is presented, as well as the expected results of the pilots.
- An iterative process to extract value from maintenance projectsPublication . Mejía Niño, Carolina; Albano, Michele; Jantunen, Erkki; Sharma, Pankaj; Campos, Jaime; Baglee, DavidResearch and development projects are producing novel maintenance strategies and techniques. Anyway, it is not straightforward to transfer results from the lab to the real world, and thus many projects, both internal to a company and in cooperation between the members of a consortium, speculate how to perform this feat, called “exploitation” in the context of European projects. This paper discusses the necessity of novel techniques in modern maintenance, and then introduces a novel approach to the problem of transferring innovation from the lab to the market. The novel approach spawns from the “spiral software development” process and proceeds as a set of iterations that bring together different stakeholders to increase the number of products, techniques and results in general that can survive the end of a research and development project. The approach was applied to a large European project, which is described as use case, and the paper reports on the encouraging results that were attained.
- An Open Source Framework Approach to Support Condition Monitoring and MaintenancePublication . Campos, Jaime; Sharma, Pankaj; Albano, Michele; Ferreira, Luís Lino; Larrañaga, MartinThis paper discusses the integration of emergent ICTs, such as the Internet of Things (IoT), the Arrowhead Framework, and the best practices from the area of condition monitoring and maintenance. These technologies are applied, for instance, for roller element bearing fault diagnostics and analysis by simulating faults. The authors first undertook the leading industry standards for condition-based maintenance (CBM), i.e., open system architecture–condition-based maintenance (OSA–CBM) and Machinery Information Management Open System Alliance (MIMOSA), which has been working towards standardizing the integration and interchangeability between systems. In addition, this paper highlights the predictive health monitoring methods that are needed for an effective CBM approach. The monitoring of industrial machines is discussed as well as the necessary details are provided regarding a demonstrator built on a metal sheet bending machine of the Greenbender family. Lastly, the authors discuss the benefits of the integration of the developed prototypes into a service-oriented platform, namely the Arrowhead Framework, which can be instrumental for the remotization of maintenance activities, such as the analysis of various equipment that are geographically distributed, to push forward the grand vision of the servitization of predictive health monitoring methods for large-scale interoperability.

- Application system design – energy optimizationPublication . Albano, Michele; Castiñeira, Rodrigo; Desdouits, Chloé; Lino Ferreira, Luis; Le Guilly, Thibaut; Isasa, Inge; Jokinen, Jani; Kondratjevs, Kaspars; Kunicina, Nadezhda; Manero, Lorenzo; Milo, Aitor; Monge, Javier; Le Pape, Claude; Pedersen, Per; Pedersen, Torben; Olsen, Petur; Siksnys, Laurynas; Skou, Arne; Stluka, Petr; Zabasta, AnatolijsIn this chapter, we present a number of applications of the Arrowhead Framework with special attention to services related to awareness and optimization of energy consumption. First, we present the notion of FlexOffers as a general mechanism for describing energy flexibility. FlexOffers can be aggregated into larger flexibility units to be used as an Arrowhead service in the virtual market of energy [1]. This is followed by two examples on how to exploit such a flexibility service in the energy management of heatpumps and a campus building. Then we present two examples on how to exploit renewable energy to provide elevator services. Next, two examples of context aware services are described – smart lighting and smart car heating, and finally it is described how the Arrowhead Framework can play a role in the optimization of municipal service systems. In the final section, we indicate future work.
- Architecture to Support Quality of Service in Arrowhead SystemsPublication . Albano, Michele; Garibay-Martínez, Ricardo; Lino Ferreira, LuisThe Arrowhead project [1] considers to normalize all interactions involving embedded systems by mediating them through services. The Service Oriented Architecture (SOA) paradigm is applied to both the interactions that provide the service requested by the user, and other support actions such as the authentication and registration of the devices, and the services they provide, the look-up of devices and service provided, and orchestration of services for creation of more complex services. To this purpose, services are divided into Core Services, which are present in every environment supporting Arrowhead applications, and user services that implement the applications. The Core Services set comprises, at least, Authentication Service, Registration Service and Orchestration Service.
- Arrowhead Framework core systems and servicesPublication . Delsing, Jerker; Eliasson, Jens; Albano, Michele; Varga, Pal; Ferreira, Luís Lino; Derhamy, Hasan; Hegedus, Csaba; Puñal Pereira, Pablo; Carlsson, OscarIn chapter 2 local clouds was discussed followed by a local cloud automation architecture in chapter 3. The automation architecture supports the implementation of local automation clouds. Such implementation is supported by the Arrowhead Framework and its core Systems and Services. The Arrowhead Framework core systems enables the creation and operation of local clouds. First implementation of these systems and their services are described in detail in this chapter. There currently are two types of core services within the Arrowhead Framework: - Mandatory core systems - needed to establish the minimal local cloud - Automation support core systems – extending local cloud capabilities intending to provide support for the design and operation of local automation clouds an interaction between local clouds.
- CANDi: context-aware node discovery for short-range cooperationPublication . Alam, Muhammad; Albano, Michele; Radwan, Ayman; Rodriguez, JonathanMulti-standard mobile devices are allowing users to enjoy higher data rates with ubiquitous connectivity. However, the benefits gained from multiple interfaces come at an expense—that being higher energy consumption in an era where mobile devices need to be energy compliant. One promising solution is the usage of short-range cooperative communication as an overlay for infrastructure-based networks taking advantage of its context information. However, the node discovery mechanism, which is pivotal to the bearer establishment process, still represents a major burden in terms of the total energy budget. In this paper, we propose a technology agnostic approach towards enhancing the MAC energy ratings by presenting a context-aware node discovery (CANDi) algorithm, which provides a priori knowledge towards the node discovery mechanism by allowing it to search nodes in the near vicinity at the ‘right time and at the right place’. We describe the different beacons required for establishing the cooperation, as well as the context information required, including battery level, modes, location and so on. CANDi uses the long-range network (WiMAX and WiFi) to distribute the context information about cooperative clusters (Ultra-wideband-based) in the vicinity. The searching nodes can use this context in locating the cooperative clusters/nodes, which facilitates the establishing of short-range connections. Analytical and simulation results are obtained, and the energy saving gains are further demonstrated in the laboratory using a customised testbed. CANDi saves up to 50% energy during the node discovery process, while the demonstrative testbed shows up to 75% savings in the total energy budget, thus validating the algorithm, as well as providing viable evidence to support the usage of short-range cooperative communications for energy savings.
