We describe collaboration models in Web services, and how to achieve universal access in the heterogeneous devices including conventional desktop PCs and mobile devices. We discuss how a rich synchronous and asynchronous collaboration environment can support virtual communications built on top of Web service infrastructure based on industry standard portal technologies, such as XML, Apache proj...

Through a broad survey of potential and existing users of mobile commerce, we attempt to address these issues. Our aim is to identify key drivers of use and potential patterns of adoption, and to develop a descriptive context of the technology’s future. Research has shown that adoption of an innovation is a function of the alignment between the innovation’s capabilities and market needs. A usef...

The mobile (wireless) service market has been rapidly growing along with the development of a variety of wireless applications and services and the increasing number of mobile Internet users. In this rapidly changing market environment, understanding users’ satisfaction with mobile Internet service, the dimensions of service quality, and their intentions to use current service is important to b...

The next generation of Internet applications is emerging: Web services. In this work, we present novel techniques for a flexible and reliable execution and deployment of Web services which can be integrated into current service platforms. Dynamic service selection allows selecting Web service instances during runtime by means of semantic classifications. The selection can be influenced by speci...

Highly mobile people (HMPs), such as international executives, airline crew, international sportspersons and independent travellers require flexible, reactive service delivery due to their regularly changing location and activities and the lack of a wired network connection. A mobile service delivery system should be able to detect relevant events such as change of location, sales opportunities...

This paper proposes a framework for which agents can be used for providing web services to mobile users. It describes a set of obliging agents distributed over different sites that work together to provide web services for mobile users. Mobile agents are programs dispatched from a client mobile device to the server to achieve a task. This is much more dynamic than client-server paradigm in whic...

The Web services technology has received significant momentum in recent years, because it allows people to easily utilize and integrate existing software applications to rapidly create new business services. However, how to ensure the trustworthiness of a Web services-oriented system remains a big challenge. One critical issue is how to test a Web service in an effective and efficient manner. I...

Mobile devices enabled with Web services are being considered as equal participants of the Web services environment. The frequent mobility of devices and the intermittent disconnection of wireless network require migrating or replicating Web services onto adjacent devices appropriately. This article proposes an efficient method for migrating and replicating Web services among mobile devices thr...

Nowadays Web based social networks are becoming more and more popular. As the functions of social networks are increasing it is reasonable to consider how mobile devices can connect to them. The paper is based on our experiences of implementing a Web based system which functions are available from mobile phones via Web services. A mobile client was also implemented that way the special abilitie...

Web Services have started to appear on servers as interfaces between business-to-business applications. To date, mobile devices have only consumed Web Services running on stationary servers. We expand this notion so that mobile devices can both offer and consume Web Services. We discuss some interesting classes of applications that can be enabled when mobile devices can host Web Services. This ...
