CFP Special Session on Sensor Networks

Optimal crisis management requires efficient and reliable situation assessment, which can be based on relevant information obtained from sensor networks and humans. However, situation assessment in crisis management settings is associated with unique challenges which require substantial research and development in many complementary areas.

Development of complex sensor networks requires research on sensing technologies, network configuration paradigms, efficient communication as well as sensor management techniques. Sensor networks should be able to integrate very heterogeneous information sources, such as simple stationary sensors, mobile sensor suites, advanced stand-alone sensors (e.g. satellites) or even virtual sensors based on predictive models. Such integration requires compatibility between heterogeneous information systems which can be achieved only through theoretically and technically sound approaches to communication and information processing.

Also, in crisis management settings constellations of information sources often change during operation; parts of sensor networks might be disabled, ad hoc networks could be formed at runtime by using mobile sensor suites, etc. Thus, sensor networks should be able to adapt to changing constellations of information sources through self configuration. An important issue is also efficient management of complex sensor networks.

By merging information from different sources the quality of situation assessment can often be enhanced. However, this requires Information processing paradigms which support quick and reliable interpretation of large quantities of heterogeneous and noisy information.

Challenging theoretical as well as practical problems are associated also with the acquisition and processing of very uncertain and subjective information that can be obtained from humans. Namely, due to the lack of dense and reliable sensor networks, situation assessment in crisis management applications often relies on information originating from humans, which can be accessed through the existing communication infrastructure (e.g. GSM networks).

In addition, automated situation assessment systems must be integrated into mission critical decision making processes. This introduces challenging problems associated with the presentation of the assessment results, human machine interfaces, development and maintenance of complex information systems, efficient approaches to validation, etc.

Session chairs: Gregor Pavlin, Nicolas Lewyckyj and Benny Carle.
