High-level enterprise services are considered as wrappers of business processes and ICT capabilities in enterprise architecture. Enterprise services have distinctive features that are not typically observed in Web services, e.g. signicant portions of the functionality of these services might be executed in a human-mediated fashion. As such, a service level agreement should be described as a mixture...
To integrate different types of devices around Erhai, China, a three layer architecture is introduced. Edge computing nodes are inserted between the server system and the end devices. A metadata model is proposed to unify the representation of devices, measurement and the interactive message between the web services and devices. The edge nodes firstly function as translator between the web services...
The paper presents the application of the RFID technology in the international system of the European Union (EU) border control. The proposed architecture consists of computerized portable units (equipped with specialized devices for data acquisition) carried by border officers and the server cloud infrastructure. Among other details of the proposed system (such as QR codes or images of people trying...
This work presents a preliminary proposal of a simple architecture for the development of heterogeneous applications, in order to allow the interoperability of applications in digital TV, mobile and web, for its incorporation in IoT. An MDA-based architecture is presented to develop applications based on a high-level abstraction, for which a brief review of MDA concepts and the state of the art is...
Domain-specific modelling is used to construct and realise the different application models upon the same specific domain for software reuse. The paper integrates domain-specific modelling and web service techniques with model-driven development, and proposes a unified approach named SODSMI (Service Oriented executable Domain-Specific Modelling and Implementation) to build the executable domain-specific...
The efforts and findings of the last decades of research on the formalization and the verification of Web services have given a certain level of assurance on Web services. However new challenges such as high availability and security issues are not fully addressed. In fact, Web services are exposed to attacks that appear continuously. These issues have naturally paved the way to a new research topic...
In this paper we present a system architecture for trust management inspired by a human model for the evaluation of trust. We focus on large-scale marketplaces for diverse software resources and services. In such marketplaces, user agents (consumer, provider and broker) are largely autonomous with vastly diverse requirements, capabilities, and trust preferences. We hypothesize the need for personalized...
The mobile and wireless networks used extensively by Internet of Things devices, are becoming more popular for data transfer between Cyber-Physical Systems. These are accessed through mobile applications installed on mobile devices, with various operating systems. The paper is presenting a Cyber Physical Systems Oriented platform for mobile transactions, with applications in remote services access...
Food related web services, such as recipe websites and food journaling apps, are rapidly gaining popularity. Data from service providers and that generated by users often coexist in these services. Compared to the former, the latter, due to its randomness and lack of organization, is often difficult to incorporate into common service features like recommendation making and associative searching. This...
Program autotuning is becoming an increasingly valuable tool for improving performance portability across diverse target architectures, exploring trade-offs between several criteria, or meeting quality of service requirements. Recent work on general autotuning frameworks enabled rapid development of domain-specific autotuners reusing common libraries of parameter types and search techniques. In this...
The use of digital content is increasing day after day and now it is an essential element of our day today life. The amount of stored information is so huge that it is highly difficult to manage the content especially in a distributed cloud environment. There are many open source software solutions available in cloud to handle huge amount of digital data. However none of these solutions addresses...
This paper presents a case study of an application prototype for shipbuilding industry using RESTful web service. Majority of database applications for traditional enterprises are based on the two-tier with simple client-server or the three-tier with additional RPC middleware. Because the outdated old configuration is not extensible, an alternative is required to link the database to the Web or mobile...
For Software Defined Network(SDN), security is an important factor which affects its large-scale deployment. The existing security solutions for SDN mainly focus on the controller itself, which has to handle all the security protection task by using the programmability of network. It will undoubtedly bring the heavy burden to the controller. More devastating, once the controller itself is attacked,...
This paper presents a distributed architecture for asynchronously implementing a class of nonlinear signal processing systems as web services, which in turn can be used to solve a broad class of optimization problems. As opposed to requiring specialized servers, the presented architecture requires only the use of commodity database backends as a central resource, as might typically be used to serve...
The significance of anomaly detection is increasing as a result of the rapid increase in unknown attacks. With the increase in deployment of scalable web services, there is a need for developing a scalable anomaly detection mechanisms. In this paper, we propose a scalable anomaly-based Bot Detection Architecture (BotD) in which different anomaly-based bot detection algorithms can be implemented. Our...
Web services play an important role in today's business computing environment for the development of distributed applications across different networks. With the rapid growth of web services on the internet, it is increasingly challenging to find the 'right' web service that meets service requesters' functional and non-functional requirements. To facilitate the effective retrieval of web services,...
As the number of network connected devices in an industrial system increases, the management and handling of all the information generated become a challenge. In this work we explore concepts of Cyber-Physical System model the virtual part of industrial devices (sensor, machines, CLPs) using the Digital Twin concept and propose an architecture based on web services for accessing their data. We present...
This paper presents the design of an assistive mobile robot to support people in their everyday activities in office and home environments. The contribution of this paper consists in the design of a modular component-based software architecture that provides different abstraction layers on top of Robot Operating System (ROS) to make easier the design and development of service robots with ROS. The...
Model checking tools for complex cyber-physical systems are increasingly being invoked online and incrementally in machine-to-machine scenarios, and executed on remote large scale compute resources. To support these scenarios in a uniform and standardized way, we present the web service WUppaal that provides formal verification of timed automata using the Uppaal model-checker. WUppaal provides easy...
In Today's world Mobile devices are the important handheld devices spreading throughout the world, and it is necessary to integrate web services into the mobile device. We introduce a simple approach for dynamically invoking web service methods from mobile devices with minimal user intervention that only involves entering a search phrase and values for the method parameters. This energy efficient...
