In this paper, we introduce a mobile services environment, namely SMOP, in which semantic web based service capability matching and locationaware information gathering are both used to develop mobile applications. Domain independency and support on semantic matching in mobile service capabilities are the innovative features of the proposed environment. Built-in semantic matching engine of the e...

The restrictions arising from the use of mobile components requires the design of a mobile infrastructure able to react to changes in the environment. We deene an application aware adaptation architecture to cope with mobile computing constraints, where interacting objects use adaptation rules to sense and react to environment variations. This mechanism, provided by a mobile service, is built w...

With the rapid development of mobile communication and computer network technologies, the new mobile learning mode has been accepted by more and more people. In this paper, taking the learning system under mobile environment and from the perspective of necessary theoretic knowledge and relative technologies for mobile learning, the structural frame of the mobile learning system was discussed an...

Mobile computing is a new and challenging technology which will deenitely revolutionize the way we use computers in the next decade. A mobile computing environment consists of stationary supporting servers and a set of mobile computers connecting to the servers by a low-bandwidth wireless network. The main diierence between a traditional client-server environment and a mobile computing environm...

Mobile ad hoc networks (MANET) are constructed by mobile nodes without access point. Since MANET has certain constraints, including power shortages, an unstable wireless environment and node mobility, more power-efficient and reliable routing protocols are needed. The OLSR protocol is an optimization of the classical link state algorithm. OLSR introduces an interesting concept, the multipoint r...

The dynamics of mobile systems require applications to intelligently adapt to changes in system configurations and to their environment. We describe a workplace in which users interact with a number of stationary and mobile systems through the course of a day. The relationship between systems and devices is constantly changing due to user mobility. We present a facility for mobile application c...

Pervasive computing is an emerging technology that brings new dimensions to distributed computing; it uses a wide variety of smart, ubiquitous devices throughout an individual’s working and living environment. Mobile agents are software entities that can migrate between servers or mobile agent environments of the network accomplishing various tasks on the behalf of their owners. The objective o...

The impact of mobile devices in our life is increasing continuously. Especially the integration of mobile devices into an enterprise environment is a hot topic these days. The following paper should give an overview about the state of the art of features, concepts and challenges of mobile operating systems to integrate them into an enterprise environment. Therefore it is necessary to show what ...

In the near future a large number of clients carrying portable multimedia terminal will access multimedia information over wireless links. The realization of such services requires the development of multimedia information servers that provide multimedia streams for mobile clients. In this paper, we identify the new requirements of multimedia information servers in mobile computing environment....
