EKG monitoring over Wireless Sensor Networks & DDoS vulnerabilities

This specialist book investigates issues related with remote monitoring of EKG signals over commercial wireless sensor networks under various network conditions. The popular wireless sensor networks with default configurations were found to be unable to support transmission of a good quality EKG signal. To improve the quality of EKG signals over the wireless sensors, some open source solutions were tested to improve end-to-end transmission and remote display of the EKG signal. The customized solution comprised of an open source application namely OscilloscopeRF for collecting and sending EKG signals from the remote patient's location over wireless sensors. Two other applications called Oscilloscope GUI and Serial-Forwarder were tested for displaying good quality EKG signals on the remote computer. To further stress test the system, Distributed Denial of Service (DDoS) attack conditions were created in the network environment to study the effect DDoS vulnerabilities on the collected EKG signals. The silent DDoS attack conditions in the network were found to alter the collected EKG signals, making it appear falsly as if the patient was having abnormal heart rhythms.
