In this work, localisation of a source within an absorbing medium is considered. By an absorbing medium, the authors mean an environment where the signal power decays exponentially with distance. The authors assume that the source is heard by nearby sensors when transmitting and its position shall be estimated based on the received signal strength (RSS) by these sensors. Under these assumptions, the...
Long-term implantable devices communicating with receivers in the outer human body through a wireless interface are one of the most prominent applications of micro/nano-technology in medicine. Ultra wideband (UWB) interfaces have great potential for the communication links of these telemedicine applications due to their inherent low power consumption, high transmission rates, and simple electronics...
Capsule endoscopy is an increasingly popular alternative to a tube-based endoscope used in diagnosing gastrointestinal diseases. It enables the inspection of areas that are not easily accessible using traditional endoscopy and reduces patient discomfort. In addition to transferring high-capacity demanding image data, the capsule's wireless interface must provide a wireless link that enables real-time...
Despite tremendous development in wireless sensor networks, the abilities are far from fully leveraged in the case of the transmission of medical sensor data. We investigate how a heterogeneous medical wireless sensor network, generating periodic data from different medical sensors, can be optimized in terms of throughput and delivery ratio. By utilizing the property of periodicity, we have implemented...
The use of biomedical sensor networks in complex clinical diagnostics and treatment may provide greater flexibility for both patient and the medical staff as some of the same sensors could follow the patient throughout the cycle of treatment. Biomedical sensors usually transmit periodically with known intervals and may require medium to higher data rates and lower packet drop rate than most traditional...
Despite tremendous development in wireless sensor networks, the abilities are by far yet fully leveraged in the case of online analysis of medical sensor data. We investigate how a data stream management system can be used to query and analyze streaming data from different medical sensors in real-time. By using the open source data stream management system Esper, we have implemented queries, based...
