Error-resistant RFID-assisted wireless sensor networks for cardiac telehealthcare

Wireless transmission of a patient’s electrocardiogram (ECG) signals can be used to reduce cardiac healthcare cost. However, wireless transmissions have high error rates due to radio interference. The ECG signal, where every second of data could mean abnormal patterns, cannot tolerate such losses. Due to this healthcare crisis, the ability for a device to remotely monitor a patient’s medication intake and transmit accurate ECG readings, while being cost efficient, is a major innovation. In this research, we integrate a multi-hop wireless sensor network (WSN) with Radio Frequency Identification (RFID) readers. Our system has two distinct features: 1) remotely supervise patient medication intake via RFID technology, and 2) accurately and remotely transmitting a patient’s ECG by adopting Extended Kalman Filter (EKF) for wireless error recovery.
