Wearable IoT EKG Signal Data Synchronization via UDP.

IoT wearable devices that leverage the LPWAN (Low Power Wide Area Network) connectivity, in particular the NB-IoT (Narrow Band IoT) technology, commonly rely on UDP (User Datagram Protocol) packets to communicate with the endpoint to collect data. Its advantage is that of minimal bandwidth usage but its drawback is the lack of acknowledgements by the endpoint. One option is to use TCP (Transmission Control Protocol) or implement a custom acknowledgement protocol at a superior level in the network stack. This paper presents the implementation and testing of a simple and lightweight software synchronization layer on top of the UDP protocol, for the transmission of live EKG signal data, with verification of data integrity and the detection of sampling points loss.
