Centre for Wireless and Sensor Systems (WiSe)

Prof. dr. Paul Havinga, Dr. Geert Heijenk


The Centre for Wireless and Sensor Systems aims its research at wireless networked systems for sensing and control. Typically, such systems operate in the context of Cyber-Physical Systems, which integrate networking, computation, and physical processes. The research of the centre ranges from radio transmission systems, and wireless network systems to sensing and control, always in close connection with the (extremely demanding) applications. The WiSe centre is focusing its research on system that are highly distributed and that can potentially scale to an extremely high number of nodes. The Centre will focus its research on a few application areas where the specific requirements and environmental conditions of the application put a very strong demand on the supporting system.

Relevant application areas are for example:

Smart and green transport
Intelligent Transportation Systems (ITS) rely on Vehicular Networks to make road traffic safer, more efficient, and more environmentally friendly. Vehicular networks can supplement a vehicle’s control systems with information sensed by other road participants, and ultimately provide coordinated distributed control of the entire traffic system.

Participatory and opportunistic sensing
in which people carrying mobile phones form a network of mobile sensor nodes and through an interactive process participate in data gathering, analysis, and sharing. This new and emerging paradigm will enable applications for e.g. smart cities, safety, and environmental monitoring.

Public Safety
Public protection and disaster relief operation relies on the timely availability of accurate information regarding potential and actual threats to public safety. Wireless and sensor systems used for monitoring and disaster recovery can greatly increase the effectiveness of public safety systems and organisations.


Scientific Challenges

The main scientific challenges for the Centre for Wireless and Sensor Systems are the following:

  • how to deal with the huge scale (e.g., number of nodes) of systems?
  • how to meet the very stringent reliability and real-time requirements when wireless systems are used for controlling, e.g., moving objects such as vehicles
  • how to make models that can predict the joint behaviour of the application or control system (at hour time scale) and the underlying wireless system (at microsecond timescale) at a realistic scale of millions of nodes?
  • how to deal with the huge amount of data involved, both in networking, as well as in storage and processing, possibly in an integrated way?
  • how to realize robust radio communications in harsh environments?
  • how to provide scalable and flexible implementation platforms for WiSe systems?
  • what techniques can be used to realize WiSe systems that are extremely energy efficient, and compatible with energy harvesting.
