Developing applications with intelligent context access capabilities is challenged by the difficulty of obtaining advanced context information. The complexity of the logic required for processing context information adds another barrier for developing advanced context-aware applications. In this research paper, we propose a solution that allows context information sharing and extension toward the...
Enterprise integration is one of the crucial challenges faced by modern organizations. Existing effort to define Enterprise Integration Patterns (EIPs) helps organizations to build their integration processes. An EIP represents a regularity in mobile agent behavior designs. In a complex distributed environment, such as mobile context, EIPs are a large number of patterns that describes the interactions...
Over the last decades, there has been a growing interest to Service Oriented Computing (SOC) especially in a mobile environement. Web Services are the most common form of services for implementing SOC. Service Composition is to create a new business process by composing several services in order to fulfill business goals that individual services cannot achieve. The massive use of web services in the...
The discovery process has become an important task in the web service life cycle as the number of Mobile Web Services (MWS) has increased nowadays. However, discovering relevant MWS that can match a service request with the service offered has remained a major hindrance. The challenges are concerning the web service discovery with the limitation of mobile devices related to performance. On the other...
The use of mobile devices as data service providers is on the rise. Mobile devices feature a large set of distinct characteristics that qualify them to be the most convenient computing platform for online services, both as consumers and providers. Mobile devices can take advantage of their mobility to provide location-based services and their association to a specific user to customize service offerings...
Mobile devices with their various form factors have become the most convenient and pervasive computing platform, whether to carry out everyday business or to get online. Mobile users tend to adopt the fast food trend even in consuming online mobile services and functionalities. The Web service approach promises great flexibility in offering software functionality over the network, while maintaining...
Due to the popularity of smartphones, finding and recommending suitable services on mobile devices are increasingly important. Recent research has attempted to use role-based approaches to recommend mobile services to other members among the same group in a context dependent manner. However, the traditional role mining approaches originated from the domain of security control tend to be rigid and...
Additively to the emergence of wireless networking, high technology and reliability of mobile devices have enabled the widespread use of mobile computing. Currently, this last is in vogue and booming. Today, the combination of mobile networks with Web Services called "Mobile Web Service", opening a promising horizon for the economy. They offer (Mobile Web Service) new personalized services...
Mobile Applications are rapidly emerging as a convenient medium for using a variety of services. In ubiquitous environment, the challenge relies on developing applications that sense and react to environmental changes to provide a value-added user experience. This context awareness property improves application usability. Context information can be related to the environment, user but also to the...
This research summary outlines results achieved by Hamburg University during its participation in the EU NoE “S-Cube” focusing on process instance migration. It includes corresponding results in the context of dynamic and mobile environments (as, e.g., provided by mobile web services, NFC-aware process execution, future-context-aware applications or interactive workflows) and focuses on the management...
The development of context-aware applications has been the subject of many research works in ubiquitous computing. As the modern human is getting more and more mobile, carrying an ever increasing amount of computational power around and having access to online services, the need for personalized and adaptive information services is rapidly increasing. Thus, the field of context-aware services has...
In this paper we consider ontologies as knowledge structures that specify attributes of services, their properties and relations among them to enable finding semantic similarity between service descriptions and service requests. Ontologies reflect semantic relationship between concepts represented by attributes in service descriptions and service requests. We use knowledge from ontologies to enhance...
The explosive growth of mobile devices and wireless networks has raised the interest for information and online service access anywhere and anytime. Due to user mobility, users will have a much closer relationship with their surrounding physical environment and will thus have a much stronger need for search and consume services that are relevant to that environment. This need has driven the development...
One of the primary issues in pervasive computing is the adaptation of the communication to the needs of limited devices. Web services are one of the technologies that present both big challenges and big potentials when it comes to their adapted usage in pervasive systems, because they carry communication overhead in order to support interoperability and platform-independence through self-description...
Applying Web service in mobile peer-to-peer service provisioning enhances the interoperability and resolves the heterogeneous challenges of ubiquitous environments. However, due to the nature of mobile peer-to-peer environments, a central repository for assisting service discovery is nonexistent, service discovery process relies on routing techniques, which increase the latency of the service interaction...
The creating of reusable mobile solutions is influenced by many factors. The platforms are arbitrary, the target audience can be new to mobile software, and the devices are not always online and restricted in their computational capabilities. This paper presents an archetype pattern- and REST-driven approach for building customizable, flexible, and efficient mobile business applications. Furthermore,...
This paper proposes and integration platform for mobile services, based on Service Oriented Architecture (SOA)and Semantic Web technologies. Mobile technology has revolutionized many aspects of our lives. The wireless infrastructure is now capable of supporting applications and services in various domains such as transport, medicine and tourism, by providing increased coverage and quality of data...
Mobile applications are increasingly taking advantages of the diverse geospatial web services to meet the information needs of their users. However, matching available web services to user's information needs is not a trivial task, as there are many contextual factors that may influence the fitness of use. In addition, mobile activities can be highly dynamic and interleaving, which demand certain...
The “Web of Things” vision promotes the integration of smart devices into web, using web technologies and protocols as underlying interaction mechanisms with smart devices. Technically many phones include various sensors and provide a large-scale sensing platform. To make this functionality available to a large number of (web) developers our research aims at easing the creation of applications that...
With the recent popularization of smart phones, context sharing systems in mobile environment attract attention of people. Mobile context sharing systems can share more information than web-based social network services because they have various sensors. For sharing high-level contexts such as activity and emotion, a user had to manually annotate them in previous works. This paper proposes a mobile...
