Electronic Product Code (EPC) and the Internet of things are developing fast with broad application prospect, thus research is done on its data processing technologies. Vending machine real-time data identified by EPC is obtained through wireless Internet of things. This data is described using Physical Markup Language (PML) after data mergence, then data middleware is used to do further processing...
The emergence of XML-based web services as a new software development paradigm increases the expectations of getting better software that address the various collaboration demands over Internet between organizations, or what's termed virtual Organization (VO). The development of appropriate identity management systems between these heterogeneous security domains will be the key enabler for such collaboration...
The following topics are dealt with: parallel processing; distributed processing; operating systems; middleware; scheduling; load balancing; computer networks; multiprocessing systems; mobile computing; pervasive computing; software development; Web services; wireless networks; data security; and cloud computing.
This paper proposes a method for the semantic integration of information systems that aims at shifting the main focus of the integration efforts, which is typically placed on software development, in the direction of business modeling with the goal of reducing the necessary code development and maintenance efforts. Proposed approach follows the principles of Web 2.0, which strongly promote the simplest,...
The enormous growth of Peer-to-Peer networks have evolved new breed of applications. A Web Service is a middleware technology which supports interoperability among the heterogeneous systems. The power of Web Service when coupled with Peer-to-Peer networks can make Web Services accessible by any small group of users to a very larger group of peers constructed over Internet. This approach enables peer-to-peer...
The advent of mobile computing devices and development of wireless and ad-hoc networking technologies has led to growth of infrastructure-less environments. Mostly, these environments lie at the edges of Internet i.e. they are disconnected/sparsely connected to rest of the world. In order to exploit the access to such edges of Internet, we propose and experimentally evaluate an interoperability middleware...
This paper focuses on the conditions for obtaining real symbiotic applications in the e-Government domain. Specific services have to be delivered to the citizens with the help of civil servants. Ambient intelligence can help the interaction between citizens and specific services only if a rich middleware based on semantics has been previously designed. We propose an approach for improving the accessibility...
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...
With the rapid development of Internet technology, web information system has achieved great development, and XML, as the new carrier and standard of information exchanging and calculating on the internet, has been widely used as well. While providing a uniform syntax and semi-structured data model, XML does not express semantics but only structure. This paper combines the web data integration problem...
Wireless sensor networks (WSN) are getting increasingly attractive as a means to bridge between the physical and the virtual world. The current trends in communication see vast advances in wireless connectivity, leading to dynamic and complicated systems on top of which applications must be built. The task of designing these applications with such systems thus becomes much more complex. One common...
The following topics are dealt with: software evolution; Word Wide Web; security of data; user interface; computer graphics; service-oriented system; software testing; data visualization; computer science education; and middleware.
Modern web-based applications are often built as multi-tier architecture using persistence middleware. Middleware technology providers recommend the use of Optimistic Concurrency Control (OCC) mechanism to avoid the risk of blocked resources. However, most vendors of relational database management systems implement only locking schemes for concurrency control. As consequence a kind of OCC has to be...
The use of sensor networks and embedding these sensory environments into the legacy systems increase the complexity and advances the level of existing integration and interoperability problems. Apart from handling the massive data produced by each component in that kind of systems, adding more heterogeneity to the already heterogeneous architectures creates a great deal on the management side of the...
With the increasing of space resources on the Internet, we need a higher demand on the spatial data sharing and knowledge discovery for the heterogeneous distributed data, but the WebGIS only can provide the parts of space resources sharing. In order to solve this problem, in this paper we put forward a solution which used for the spatial data mining and knowledge discovery in the grid environment,...
A number of multi-media applications are growing in the Internet, many Web sites are frequently faced with the problem of overloading the server. IP networks can not guarantee a specific QoS service requirement, which has become tremendous obstacles to develop IP networks into broadband integrated services network. This paper analyzes Web based on campus network and proposes based on the distinct...
Distributed simulations are mainly used to interoperate heterogeneous simulators or geographically distributed models. We present here RESTful-CD++, the first distributed simulation middleware based on REST (Representational State Transfer) Web-services. RESTful-CD++ middleware enables heterogeneous independent-developed simulation components to interoperate with much flexibility and simplicity. REST...
In the domain of industrial automation the interoperability of devices gains importance. One major trend is the usage of Ethernet based solutions to connect devices at all levels of a company. Through a common interface technology in all levels of execution, a central control mechanism or business flows can control an entire workflow. This paper describes a new RESTful oriented device architecture,...
In the modern world, the business between enterprise and customers or enterprise and enterprise is interactived by Internet in most of the time. So it needs to make sure the identity of the interviewer, then protect the exchange message. This article is based on SOA, adapt the Java business integration, researched the application of middleware for signature stream, to imply loosely coupled integration...
In large-scale RFID applications, RFID middleware has played a very important role. Most popular RFID middleware serves as RFID reader manager, data processing center, data distribution and subscription server, which means all work is done by one server. When there are a large number of readers, the only way to increase processing capacity is to add more servers. Since every server is an independent...
Modern Smartphones are the fastest growing computing platforms capable of consuming Web services. However, due to their form factor these mobile computing devices face many challenges and constrains when engaging service providers. How to overcome these challenges and how to link smartphones to the service cloud is one of the key issues that will have a major impact on the further growth of the software-as-a-service...
