The benefits of utilizing service oriented architectures (SOA) in industrial automation are well recognized. Nevertheless these architectures imply connection establishments and message exchanges with a large amount of overhead which is inappropriate when considering the real time characteristics of an industrial application. Furthermore, wireless sensor networks (WSNs) which are often part of such...
We describe the conclusions of a technology and communities survey supported by concurrent and follow-on proof-of-concept prototyping to evaluate feasibility of defining a durable, versatile, reliable, visible software interface to support strategic modularization of test software development. The objective is that test sets and support software with diverse origins, ages, and abilities can be reliably...
In this paper we address the problem of creating fully transparent disruption/delay tolerant networks, in which some of the links are provided by low-bandwidth acoustic modems. Our approach involved extending the DTN Research Group Reference Implementation to support the WHOI Micro-Modem, pluggable MAC algorithms and on-the-fly data compression. We have shown, in field experiments, that our software...
This paper has designed and implemented a method that automatically generates XML abstract test cases from E-LOTOS language. Through analyzing the E-LOTOS text which describes the protocols, this paper has obtained adjacency finite state machine and drew the graph with the JAVA language to show the protocol running mechanism. By using the Dijkstra algorithm and a heuristic algorithm for UIO sequence...
With the maturity of SOA and rapid development of Internet, a new type of software delivery mode named SaaS (Software as a Service) which provides the customers functionalities needed arises. It saves the cost of IT operation and suits to the small to medium firms very much. Ecommerce has grown extraordinarily nowadays with widespread Internet usage. In order to make trades more convenient and faster,...
Service-oriented Architecture (SOA) is increasingly relevant across several domains of application by promising systems openness and unification over a common design and communication paradigm. At device level, the application of SOA is carried, on one hand, by Devices Profile for Web Services (DPWS) and complementary web-based specifications oriented towards resource management, and, on the other...
On the basis of shortage existing in traditional WebGIS, this paper puts forward a novel WebGIS framework based on Ajax, Web Services and SOA. The framework combines Ajax with Web Services. Through invocating Web services asynchronously by Ajax, the problems of poor user experience, system isomeric compatibility, system integration and mutual operation etc. are solved. The conclusion means a great...
Wireless sensor networks (WSNs) have many applications in home and industrial automation, and the management and integration of WSNs into Internet and IP-based networks is still getting tremendous interesting. This paper presents a micro SOA-model as part of a 4-layered, SOA-based architecture targeting resource-constrained devices with 48 KB of ROM and 10 KB of RAM. The key idea in this model is...
The shop-level information integrated system is the glue of system integration between enterprise upper management systems and the underlying process control systems, the basic of executing enterprises' agile manufacture strategy. The field management and shop information integration are given more and more attention by enterprises, the methods and technologies of traditional shop management can't...
SOA (Service-Oriented Architecture) is an architecture model; it can carry on distributed deployment, combination and utilization to loosely coupled coarse-grained application components according to the requirement through Internet. Based on the problem of a poor adaptability existing in a Shipping E-Commerce Platform, a SOA development framework is proposed. According to Web Services technology...
Integrating voice / video communication into business processes can accelerate resolution time, reduce mistakes, and establish a full audit-trail of the interactions. Some VoIP service providers offer website based or plugin based solutions, which are, however, difficult to integrate with other applications. A promising approach to overcome these disadvantages is the development of appropriate Web...
The use of the Service-Oriented Architecture paradigm (SOA) as an architectural model together with the use of Web services technologies have spread out widely in the world of business processes. The Business Execution Language, BPEL, represents one of the most common orchestration languages used to build SOA compositions. Using BPEL, a business process can be constructed integrating different Web...
The development of applications for embedded sensor actor networks involves two major challenges: one of them is the communication between a diversity of widespread resource constraint nodes. The other one is the infrastructure dynamics. Web service based Service Oriented Architecture (SOA) would perfectly meet such unique characteristics of embedded networks and ease the development of applications...
In this paper, are presented some possibilities for application of an algebraic method which handles XML hierarchical data structures and makes faster the XML search mechanism. The article briefly presents the concepts of Web Services, Service-Oriented Architecture and other modern software paradigms for organization of the processes over internet. The accelerating techniques for XML navigation through...
Power marketing system plays an important role in customer service marketing management system, because the system involves data sharing and information application concurrently of central departments in power enterprise. It is very difficult for power marketing system to implement information sharing across power enterprise, but creating an information integrated platform to achieve information integration...
As the internet developing, web-based applications are increasingly popular in service-oriented architecture. Web service has XML support, which is the most suitable technology to achieve service-oriented architecture. Web service is essentially an interface which enables the isolations between different sites to communicate with each other. In this paper, based on .NET platform for web service and...
In this paper, we describe a practical realization of an Internet-of-Things (IoT) architecture at the University of Padova, Italy. Our network spans the floors of different buildings within the Department of Information Engineering, and is designed to provide access to basic services such as environmental monitoring and localization to University users, as well as to manage service access based on...
In the SIP-based telephone-IP convergence scenario, telecom services are typically asynchronous, require low latency, high throughput and high availability. In this scenario, platforms compliant with JSLEE specifications are good candidates to execute such services. This paper proposes a new architectural solution for service creation in JSLEE-compliant platforms. In our proposed solution, service...
Interoperable DEVS modeling and simulation is desirable to enhance model composability and reusability with DEVS models and non-DEVS models in different languages and platforms. The barrier to such interoperability is that DEVS simulators implement the DEVS modeling formalism in diverse programming environments. Although the DEVS formalism specifies the same abstract simulator algorithm, different...
The software systems grow rapidly with the development of software technologies. Traditional Enterprise Application Integration technology can not adapt to the rapid increase in the Enterprise Information Systems. In SOA, different development tools can interact with each other to realize integration. With standard protocol, Web can integrate all kinds of heterogeneous system into current system conveniently...
