Helping develop wireless Internet services

12.08.2004


New architectural guidelines to assist programmers develop wireless Internet services for 3G devices such as PDAs, camera-phones, data terminals, etc and overcome difficulties such as reduced screen sizes, varying bandwidth, handling mobility etc. were demonstrated by project WISE.



The main purpose of the architectural guidelines is to provide a unified and organised approach to the description of the software architecture. The architecture is described both from an abstract conceptual perspective and a detailed concrete one. “We use three iterations to produce a description,” says Maurizio Morisio, coordinator of this IST programme-funded project. “In each iteration we produce three papers: an abstract implementation of the service, an analysis of the processes to develop the services and architecture to support the services, and guidelines for devices. The latter specifies how to handle various characteristics that may impinge upon the services offered, such as variations in screens used, absence or presence of a keyboard or mouse, and so on.”
In practice, it’s quite complex having a generalised architecture, so WISE is using typical architectures. “We have two architectures,” says Morisio. “One corresponds to a J2ME Java Fat Client, and the other to a Thin Client which has a simpler user interface.”

In parallel with the work on architectures, WISE pilot trials have demonstrated two prototype services. “One is a game that uses mobile phone GPRS data connections, and which is played by more than one player,” says Morisio. “The second is an online trading application for high-volume share trading. It runs on a mobile phone, and is a reduced version of the RealTick service that provides a real-time display of current share prices.”



The project is currently in negotiation with a large publisher of technical books with a view to publishing the WISE architecture handbook. One of the consortium partners has signed a deal with Telecom Italia Mobile to provide the online trading service as a real commercial application.

Im Focus: Giant Magnetic Fields in the Universe

Astronomers from Bonn and Tautenburg in Thuringia (Germany) used the 100-m radio telescope at Effelsberg to observe several galaxy clusters. At the edges of these large accumulations of dark matter, stellar systems (galaxies), hot gas, and charged particles, they found magnetic fields that are exceptionally ordered over distances of many million light years. This makes them the most extended magnetic fields in the universe known so far.

The results will be published on March 22 in the journal „Astronomy & Astrophysics“.

Galaxy clusters are the largest gravitationally bound structures in the universe. With a typical extent of about 10 million light years, i.e. 100 times the...

Im Focus: Tracing down linear ubiquitination

Researchers at the Goethe University Frankfurt, together with partners from the University of Tübingen in Germany and Queen Mary University as well as Francis Crick Institute from London (UK) have developed a novel technology to decipher the secret ubiquitin code.

Ubiquitin is a small protein that can be linked to other cellular proteins, thereby controlling and modulating their functions. The attachment occurs in many...

Im Focus: Polymer-coated silicon nanosheets as alternative to graphene: A perfect team for nanoelectronics

Silicon nanosheets are thin, two-dimensional layers with exceptional optoelectronic properties very similar to those of graphene. Albeit, the nanosheets are less stable. Now researchers at the Technical University of Munich (TUM) have, for the first time ever, produced a composite material combining silicon nanosheets and a polymer that is both UV-resistant and easy to process. This brings the scientists a significant step closer to industrial applications like flexible displays and photosensors.

Im Focus: Researchers Imitate Molecular Crowding in Cells

Enzymes behave differently in a test tube compared with the molecular scrum of a living cell. Chemists from the University of Basel have now been able to simulate these confined natural conditions in artificial vesicles for the first time. As reported in the academic journal Small, the results are offering better insight into the development of nanoreactors and artificial organelles.
