With the recent advent and widespread use of smart mobile devices, the flexibility and versatility offered by Service Oriented Architecture’s (SOA) makes it an ideal approach to use in the rapidly changing mobile environment. However, the mobile setting presents a set of new challenges that service discovery methods developed for nonmobile environments cannot address. The requirements a mobile ...

The Web Services are of a vital role in the domain of mobile networks for their utility in various applications of communications field. However there are more challenging issues of functionalities of mobile technology with the current Web based resources. The work in the present paper deals with architectural implementation methodologies of the mobile technology for the enhancement of utility ...

Mobile devices have the limited environment such as low process performance, small screen size, low network speed and restricted user interface. This situation prevented the use of diverse and rich desktop-based information and services because the user could use limited services in mobile telecommunication environment. Also, this demands that service providers should develop a separate web con...

Client software for modern service-oriented web architectures is often implemented as mobile code applets made available by service-providers. Protecting clients from malicious mobile code is therefore an important concern in these architectures; however, the burden of security enforcement is typically placed entirely on the client. This approach violates the service-oriented paradigm. A method...

Due to advancements in mobile technology and connectivity, mobile devices have become fully-fledged web clients. At the same time, more and more Semantic Web data is becoming available, to a point where it becomes usable for various mobile application scenarios. However, most applications are limited to using pre-defined query endpoints in order to access Semantic Web data, which leaves a huge ...

iii Abstract The progresses in the fields of mobile Internet and positioning methods have lead to a plethora of new possibilities for cartography in mobile usage environments. However, principles of web mapping cannot simply be transferred to the mobile environment. Likewise the availability of Location Based Services (LBS) has made it possible to develop mobile map services, yet LBS themselves...

Recent advances in mobile computing have spawned a very heterogeneous environment of mobile devices. Those devices have different capabilities in providing mobile services to the user, implying the challenge of considering heterogeneous devices during mobile service development. This especially encompasses the task of adapting the content, which a mobile service provides to a specific mobile de...

Web services have been widely accepted as a platform independent services-oriented technology. Meanwhile, ubiquitous technologies are becoming popular in a variety of domain applications. In particular, hosting web services from mobile devices became a way to extend knowledge exchange and share. This paper presents our design and implementation of a mobile web service (MWS) middleware motivated...

Mobile Grid Service is the extension of Grid Service. It is defined as: it is an intelligent code service wandering in grid nodes to accomplish certain task and provide certain service. Mobile Grid Service provides a series of standard interfaces and conforms specific conventions to solve such problems as: mobile service discovery, dynamic service creation, lifetime management, notification, mo...
