To follow the technology advancement and satisfy the needs on the RTI software in the “Cloud computing” age, a scheme of remodeling the traditional RTI software to be with “Platform as a Service (PaaS)” architecture was proposed. Software construction, sub-component functions and the method of interacting based on the remodeled RTI software on the WAN were studied. The focus was scheduling computing...
With the increasing popularity of distributed systems, middleware has become a major building block for the development of distributed applications. In this paper, we firstly analyze in detail four traditional middleware systems called RPC middleware, message-oriented middleware, transaction-oriented middleware, and distributed object middleware. Subsequently, we present a detailed review of SOA,...
For future application scenarios of resource constrained and low cost smart cooperating objects, miscellaneous technologies for wireless connectivity are existing or upcoming in the near future. But further cross domain middleware and dedicated communication protocols to provide syntactic and semantic interoperability and not only technical interoperability are still missing. Thus, this paper investigates...
First of all clarify the research background, and introduces the necessary theory and techniques involved in the relevant. Through the management information system access system resources study of various control methods, using RBAC access control technology to design and implement a middleware based rights management that can run on a variety of hardware and software platform to facilitate the conduct...
Nowadays, it is very important and necessary to share calculation model and results in chemical tests system for testers who work in different place and lack of certain expensive but key test devices. This paper proposes a novel software architecture for those people to share their resources and to work collaboratively. To begin with, it brings forward the system architecture based on web service...
Event driven architectures are widely used in numerous software applications, for instance in GUI focused software. Currently most event driven softwares are applied merely in local environment. If we need to use event driven architecture in a distributed environment, there are not too many candidates to choose from. Thus, although there are a number of techniques which support the event notification...
Since OPC DA Server is base upon the technology of COM/DCOM, its technical defect has appeared prominently while exchange the data with each other between the Internet. Thus it's important to lead out the technical advantage and the necessity of OPC XML-DA Server based on the Web Service technology. The exchange of plant data across networks has been facilitated, in the meanwhile, the Data Fusion...
This paper describes the conceptual design of an interaction independence middleware framework and describes the role that web services plays within it. We investigate two pervasive service-oriented architecture paradigms, SOAP and REST, in order to gauge their potential effectiveness in meeting underlying back-end data transmission requirements; provide implementations for the service-oriented architecture...
To meets the publish/subscribe demands in personalized service, this paper focuses on WS-TOPICS, WS-base notification and WS-broker notification of WS-notifications (WSN) and use WS-resource describe one or more stateful resources which will be published as WS-TOPICS in WS-notification. Through home-school interactive example, it implements the publics/subscribe model using the notification based...
Traditionally, the composition of Web services to create mashups has been achieved by using an application server as a mediator between a client browser and services. To avoid this bottleneck, mashups are sometimes implemented so that Web service composition takes place directly from the end userpsilas browser. Creating such implementations is difficult because developers must manage the separation...
Nowadays, there is an increasing need for deploying Web services into embedded devices in pervasive computing environments. However, a number of problems arise for running pervasive web services, such as service not being accessible due to devices being located behind firewalls or NATs and therefore devices cannot offer services dynamically, and mobility problems as devices might change their location...
This paper describes the advantages of Cadabiaover competing network programming frameworks.Cadabia is a middleware service architecture for sharing dynamic classes and objects in network-based applications. A default database editor can either be run as a stand-alone RMI application or as a Web service. Cadabia queries can be used as properties of GUI components to read/update persistent data.Cadabia...
The aims system of message-driven model changes the way of data exchange based on Web Services from pull passively to push actively. The message-driven publish/subscribe gives recommended find Web Services model, it changes the way users find Web Services. The key technologies of the platform model are discussed Last verifies the feasibility of the design model combined with concrete examples. The...
As Web based software has developed recently, service via web has increased gradually. For this, many research organizations and reports call Web is the platform of software. While Web based technologies have developed, middleware of WSN and its application service has been developed from desktop based operation system. So WSN's technology reached uppermost limit of desktop application. There's difficulty...
Many scientific fields routinely generate huge datasets. In many cases, these datasets are not static but rapidly grow in size. Handling these types of datasets, as well as allowing sophisticated queries necessitates scalable distributed database systems, in which scientists are efficiently able to search the datasets. In this paper we present the architecture, implementation and performance analysis...
DrugScreener-G is an integrated environment for virtual screening with grid computing. It implements basic ideas of grid-enabled large-scale virtual screening into a concrete software suite, especially emphasizing user friendliness and accessibility to grid computing. DrugScreener-G aims at providing users without knowledge of grid computing with an intuitive and easy-to-use integrated environment...
Voice over Internet protocol (VOIP) technology has been widely adopted in communication middleware systems that allow service providers to construct web based applications, such as Web conference systems (WebEx, Gotomeeting), IP based call centers and Web chatting. VOIP is vulnerable to network congestion if too many users access the Web service based VOIP at the same time, especially the services...
Composing adaptive and self-managing Web services needs plug-and-play architecture so that the deployment of control components does not require changes made to the Web services and the host middleware platforms. This is especially challenging for Web services running on COTS middleware platforms, such as Microsoft.Net. In this paper, we propose an architectural solution that introduces a management...
Enterprise service bus (ESB) provides a layer on top of an implementation of an enterprise messaging system. The ESB provides a highly distributed, event-driven service oriented architecture (SOA) that combines message oriented middleware (MOM), Web services, intelligent routing based on content, and XML data transformation. ESB transmits and receives standard set of messages. When it receives a message,...
In a business environment, effective communication is crucial for the employeepsilas productivity and creativity. In this paper, we propose a SOA-based Collaboration Framework for mobile collaboration applications. This framework aims at promoting the business communication to a new level by means of architectural flexibility, lightweight design approach and a substantially increased availability...
