With the rapid development of the UHV power grid, the data interaction between the dispatching agencies has increased significantly, and the inter-agency integration features have become increasingly obvious. However, at present, the service bus in the dispatching control system is mainly for a single scheduling mechanism, only to achieve wide area sharing of specific application services and not...
A service-oriented architecture (SOA)-based application is composed of a number of distributed and loosely-coupled services which are interconnected to accomplish a more complex functionality. The main security challenge in SOA is that we cannot trust the participating services in a service composition to behave as expected all the time. Moreover, the chain of all services involved in an end-to-end...
In the era of Internet of Things and dynamically interconnected systems, real time data becomes a new industrial asset, used to create new opportunities for operations improvement and to increase industrial value through the capitalisation of immaterial assets. In the smart factory, big data acquisition, analysis and visualisation pave the way to the manufacturing servitization, defined as the strategic...
Digital documents are likely to have problems associated with the persistence of links, especially when dealing with references to external resources. People keep track of various webpages of their interest using distributed digital collections and without possession of these documents; the curator cannot control how they change. In the current context, managing these distributed digital collections...
In order to communicate with another service, a service needs to know the address of other services. This knowledge can be acquired by a process called service discovery (SD). In a microservice architecture (MSA), unlike SOA, a service discovery framework has not been provided out of the box. In a telecom environment additional requirements may arise, besides the basic one of discoverability. In this...
In this paper a novel architecture for control system design in networked environment is presented, where the consistent distribution of the control system functionalities is proposed to the dedicated time-aware system components. The sensing, actuating and algorithmic functionalities are uniformly encapsulated into the passive system components utilized as a network-accessible service groups. Service...
Today's Enterprises are facing many challenges in the service oriented, customer experience centric and customer demand driven global environment where ICT is becoming the leading enabler and partner of the modern enterprise. In the last decade, many enterprises have invested heavily in SOA-aligned IT transformations, but not harvested what SOA promised to provide. Now the API and Microservice paradigm...
The present paper presents a unified cloud-based framework for offering Ambient Assisted Living (AAL) services to elderly with cognitive impairments aiming at prolonging and supporting their independent living, through interoperable, open, personalised and seamless ICT solutions. Through its cloud architecture that is based on the OSGi framework, the proposed framework enables easy registration and...
Wireless sensor networks (WSN) play an important role in many applications like healthcare, traffic monitoring, security, environmental and infrastructure monitoring. When designing these applications for different domains like healthcare, traffic management or military intelligence, people face a lot of challenges. Service-oriented architecture (SOA) is an emerging area in distributed computing that...
An efficient monitoring system and communication framework for energy usage and consumption monitoring in a microgrid is the basis for any development of energy optimization policies. It also enables costs reduction and fast problem detection. Distributed Smart Energy Meters are becoming more and more useful in commercial, industrial and domestic domains, in particular when they are conceived as low...
In this paper, we suggest a service-oriented architecture for planning and execution (SOA-PE) in large scale cyber-physical systems (CPS). SOA-PE provides a clean separation between domain modeling, planning, execution, monitoring and actuation services. This approach helps realize the system-of-systems paradigm allowing the decomposition of system goals into smaller subgoals, thus enhancing the scalability...
Recently, a lot of sensors are deployed to monitor the context in heterogeneous environments. A sensor is an engineering point of view as a device that collect the phenomenon signal. The sensor middleware is to enable clients to view context data on Internet. In this paper, we propose an integration architecture based on service provider using multiple sensor middleware in heterogeneous large-scale...
Software engineering literature is rich in terms of various architectural options to build conventional software systems but very less efforts have been put forward for generic architectures to build autonomic systems. This position paper presents a hierarchical generic service oriented architecture for developing autonomic systems.
The IoT research area has evolved to incorporate a plethora of messaging protocol standards, both existing and new, emerging as preferred communications means. The variety of protocols and technologies enable IoT to be used in many application scenarios. However, the use of incompatible communication protocols also creates vertical silos and reduces interoperability between vendors and technology...
A Cyber-Physical System (CPS) is defined as integrations of computation and physical processes. In CPS, small embedded devices are used to monitor and manage the physical process. Because of these physical devices with limited resources, it is impossible to perform complex calculations and processing. In view of this situation, we apply Service-oriented Architecture (SOA) concepts to CPS, called a...
Virtual Communities (VCs) are dominating our daily activities from different insights. Social, Business, Professional, Educational and many VCs are competing to conquer the cloud by targeting more audience through the services they provide. The diversity, magnitude and quality of provided services raise a new challenge for managing these services. Consequently, the success or failure of VCs depends...
During the last 10 years, experts in critical infrastructure security have been increasingly directing their focus and attention to the security of control structures such as Supervisory Control and Data Acquisition (SCADA) systems in the light of the move toward Internet-connected architectures. However, this more open architecture has resulted in an increasing level of risk being faced by these...
Network-as-a-Service (NaaS) is a cloud-based service model that offers on-demand network connectivity and the provisioning and management of network services. However, the actual orchestration of dynamically allocating underlying resources to customer requirements is not trivial. In this paper, we propose an SDN-based approach to support the NaaS model. We implement a proof-of-concept (PoC) on a physical...
Mental healthcare can be the smart home service for ambient assisted living. In this paper, a web of objects embedded smart home architecture is presented for mental healthcare. Patients' psychiatric symptoms are collected through lightweight bio-sensors and web based psychiatric screening scales and then analyzed using machine learning algorithms.
