EMF Modeling in Traffic Surveillance Experiments

Abstract—We use a wireless sensor network equipped with acceleration sensors to measure seismic waves caused by rolling traffic. In this paper, we report on our experiences in applying an EMF-based data infrastructure to these experiments. We built an experimentation infrastructure … Continue reading

HWL — A high performance wireless sensor research network

Abstract—Current Wireless Sensor Networks (WSN) consist of low powered energy efficient nodes with short range radios and limited computation capabilities. Sensing applications with multiple sensors, high sample rates, and large spatial coverage are not realizable with conventional WSNs. We propose … Continue reading

From Earthquake Detection to Traffic Surveillance – About Information and Communication Infrastructures for Smart Cities

Abstract—Smart cities use networks of sensors, actuators, and centralized computing clusters to observe physical reality, derive information, and thereby influence citizens and authorities. Smart city applications therefore require three components to work: wireless sensor networks, geo-information systems, and frameworks for … Continue reading

ClickWatch – An Experimentation Framework for Communication Network Test-beds

Abstract—It is hard to experiment with test-beds for communi- cation networks: data produced in the network has to be retrieved and analyzed, networks must be reconfigured before and between experiments, data is often little structured (log-files) and analysis methods and … Continue reading
