Optimal online communication

24.04.2008
Dutch researcher Peter Korteweg has developed algorithms for wireless networks. The algorithms focus on optimising communication to a central point in such networks, for example, by minimising processing times and the communication costs.

An optimisation problem describes a situation in which an optimal solution is sought from among all possible solutions. Mathematicians study an optimisation problem to find a general method for solving such a problem; such a method is called an algorithm.

Korteweg has developed algorithms for wireless networks. An important problem in online networks is the communication of data to a central point in the network. The quality of the solution depends on several criteria, such as the energy cost for communication and the time needed to collect data.

Korteweg studied subsidiary aspects such as minimising the maximum communication costs, minimising the time needed to collect all data and minimising the processing time of messages.

Important results are the insight into the effect that faster communication resources can have on the quality of the algorithm, and an algorithm that ensures that both the communication costs and the message delays deviate as little as possible from of the best offline solution.

The research was carried out at Eindhoven University of Technology, and funded by a grant from the Free Competition (previously: Open Competition) of NWO Physical Sciences: www.nwo.nl/oc.

Im Focus: ScanCut project completed: laser cutting enables more intricate plug connector designs

Scientists at the Fraunhofer Institute for Laser Technology ILT have come up with a striking new addition to contact stamping technologies in the ERDF research project ScanCut. In collaboration with industry partners from North Rhine-Westphalia, the Aachen-based team of researchers developed a hybrid manufacturing process for the laser cutting of thin-walled metal strips. This new process makes it possible to fabricate even the tiniest details of contact parts in an eco-friendly, high-precision and efficient manner.

Plug connectors are tiny and, at first glance, unremarkable – yet modern vehicles would be unable to function without them. Several thousand plug connectors...

Im Focus: New Strategy Against Osteoporosis

An international research team has found a new approach that may be able to reduce bone loss in osteoporosis and maintain bone health.

Osteoporosis is the most common age-related bone disease which affects hundreds of millions of individuals worldwide. It is estimated that one in three women...

Im Focus: AI & single-cell genomics

New software predicts cell fate

Traditional single-cell sequencing methods help to reveal insights about cellular differences and functions - but they do this with static snapshots only...

Im Focus: TU Graz Researchers synthesize nanoparticles tailored for special applications

“Core-shell” clusters pave the way for new efficient nanomaterials that make catalysts, magnetic and laser sensors or measuring devices for detecting electromagnetic radiation more efficient.

Whether in innovative high-tech materials, more powerful computer chips, pharmaceuticals or in the field of renewable energies, nanoparticles – smallest...

Im Focus: Tailored light inspired by nature

An international research team with Prof. Cornelia Denz from the Institute of Applied Physics at the University of Münster develop for the first time light fields using caustics that do not change during propagation. With the new method, the physicists cleverly exploit light structures that can be seen in rainbows or when light is transmitted through drinking glasses.

Modern applications as high resolution microsopy or micro- or nanoscale material processing require customized laser beams that do not change during...
