Colloques Interfaces

Research Challenges for Distributed Sensing Applications

"Interfaces", Aquitaine scientific symposium for digital sciences. This serie of talks will host several times a year, scientists from entire world, recognized for the quality of their work and the results they produce. Topics will treat about computer sciences and applied mathematics but mostly about their intersections with others sciences and fields. Medicine, Social sciences and humanities, art, etc. are such topics that are addressed.

  • Date : 22/09/2017
  • Place : Centre de Recherche Inria - Bordeaux - Sud-Ouest, salle Ada Lovelace at 11am
  • Guest(s) : Henri Bal
  • Organiser(s) : Inria Bordeaux - Sud-Ouest

For its next edition, Interfaces •  Aquitaine scientific symposium for digital sciences , welcomes : 

Henri Bal
Professor of Computer Science at the Vrije Universiteit, Amsterdam in the Netherlands.

The talk will be held in English and will be followed by a drink.  

The field of distributed sensing is evolving rapidly. Numerous applications use smartphones and wearables for sensing human health, buildings, air quality, traffic, and safety. Internet of Things (IoT) infrastructures are becoming widely available, leading to billions of inexpensive sensor devices on the Internet. This development will come with many new challenges for Computer Science, as sensor applications typically deal with highly dynamic, widely distributed data and often need fast response times.

This talk will first sketch some relevant technological developments in sensors and IoT communication technology (e.g., LoRaWAN). Next, it will discuss research challenges for Computer Science. The wide diversity of sensor and communication technology calls for transparent mechanisms to easily process sensor data in a uniform way. The extreme distribution of sensors and the many hierarchy levels in modern distributed computing systems make the scheduling of computations highly complex. Also, higher level analytics tools should be adapted to handle dynamic (streaming) sensor data. Finally, there are many interesting questions around privacy, ethics, and economics related to future distributed sensor applications. The talk will discuss these challenges and illustrate them with examples from our recent research on programming systems and applications. Henri Bal heads a research group on High Performance Distributed Computing at the Vrije Universiteit in Amsterdam. He studies parallel and distributed programming systems in combination with real-world applications. His group produced programming environments such as the Orca language, MagPIe, Ibis, Satin, JavaGAT, and SWAN.  His current work focuses on programming environments for GPUs (Graphics Processing Units) and distributed sensor systems based on smartphones and Internet-of-Things.

Henri Bal is the winner of the Euro-Par 2014 Achievement Award, member of the Informatics Section of the Academia Europaea, scientific director of the ASCI research school, and coordinator of the DAS infrastructure.

He is past program chair of the HPDC and CCGrid conferences and author of three books, including Modern Compiler Design. He has a PhD in Computer Science from Vrije Universiteit (1989) and a MSc in Mathematics from Delft University of Technology (1982
