More efficient combinations of web services through mobile channels

31.01.2007
The 'mobile channels' software concept allows services on the web to be combined more flexibly and efficiently. How mobile channels work is described by Dutch researcher Juan Guillen Scholten in his PhD thesis 'Mobile Channels for Exogenous Coordination of Distributed Systems'.

Over the past few years there has been a growing interest among computer scientists and users for distributed computer systems such as the Internet. A distributed system consists of different independent computers in a network that appears to be a single coherent system for the users. At least one software component is present on each computer, which communicates with components that are on other computers, such as databases, web services or peer-to-peer applications that exchange data such as Skype, Kazaa or Napster. As all of these components are distributed and run at the same time, suitable theories and infrastructures are needed for an efficient coordination.

Guillen Scholten developed the MoCha coordination framework that consists of both models and software. It is capable of coordinating components from the outside (exogenously). As a result of this MoCha can change the behaviour of the system without needing to adjust the software components. It can also dynamically change the links between components. This characteristic is particularly useful when the components are mobile. MoCha can be used efficiently on Grids, in service-oriented architectures (SOAs), component-based software and in-home networks.

The National Research Institute for Mathematics and Computer Science (CWI) is the national research institute for mathematics and computer science. It is a research institute of NWO. For further information see www.cwi.nl.

Juan Guillen Scholten's research was funded by NWO.

Im Focus: Quantum optical sensor for the first time tested in space – with a laser system from Berlin

For the first time ever, a cloud of ultra-cold atoms has been successfully created in space on board of a sounding rocket. The MAIUS mission demonstrates that quantum optical sensors can be operated even in harsh environments like space – a prerequi-site for finding answers to the most challenging questions of fundamental physics and an important innovation driver for everyday applications.

According to Albert Einstein's Equivalence Principle, all bodies are accelerated at the same rate by the Earth's gravity, regardless of their properties. This...

Im Focus: Interfacial Superconductivity: Magnetic and superconducting order revealed simultaneously

Researchers from the University of Hamburg in Germany, in collaboration with colleagues from the University of Aarhus in Denmark, have synthesized a new superconducting material by growing a few layers of an antiferromagnetic transition-metal chalcogenide on a bismuth-based topological insulator, both being non-superconducting materials.

While superconductivity and magnetism are generally believed to be mutually exclusive, surprisingly, in this new material, superconducting correlations...
