With the arrival of Java 2 Micro Edition (J2ME) and its industry support 1, 2, we can now create applications that run on commonplace pervasive computing devices, such as mobile phones or PDAs. Several research groups are working on platforms for building intelligent agent applications for this environment 3, such as MicroFIPA 4, the Lightweight Extensible Agent Platform (LEAP) 5, and our Agent...

Nowadays, many of the services offered by the mobile telephony don’t provide to the user a simple and intuitive tool to fill and send information. This way, the users have to code themselves the format of the message, with the corresponding annoyance and the possibility of making errors. One of the solutions to these problems could be provide forms that the user could fill and send from their m...

This paper presents SPARTA (Secure, Policy-driven, ARchitecture for content disTribution and storAge), a secure, policy-driven architecture for enterprise applications operating in centralized wireless environments. SPARTA supports end-to-end client authentication, data integrity and confidentiality. The security services provided by SPARTA are customized and controlled by easily configurable s...

Key aspects in realizing the maximum potential of advanced Location-Based Services (LBS) are the standardization and cross-platform availability of an Application Programming Interface (API) for mobile phones that allows access to real-time location information. To shorten the development time of advanced LBS, such an API should also provide essential features such as map user interfaces, geoco...

Due to the development witnessed in the field mobile phone and the development of their operating systems added to the increase in number of users and many businesses that have relied on them, a large number of programmers have started to develop special operating systems for these phones and building applications that meet the demands of the users and facilitate a great number of businesses. T...

In this paper, we demonstrate the use of design patterns to develop games for mobile devices on the J2ME platform. We believe that the proposed idea will help J2ME game developers to write better re-usable code faster. We consider a single player Sudoku board game which is based on the model-view-controller architecture. The view is configured with a Game Controller Choice pattern so that diffe...

The article examines the problem of giving the Grid users a possibility to access their applications and resources from any place using mobile devices. According to our approach the devices are incorporated as the clients of Grid services. Moreover, because of limitations of mobile devices this approach assumes adopting a gateway between the client and the Grid. These limitations forced us to p...
