Abstract—Body area network is widely used in remote
healthcare area. In this paper, smartphone based body area
network system (SBBANS) is proposed. SBBANS is constituted
by smartphone and multi parameter monitors, using Bluetooth
and serial port for data transmission, and provides
comprehensive health information. The system is capable of
transferring data with healthcare centre servers over
3G/4G/Wlan. A simple real-time lossless electrocardiogram
(ECG) compression algorithm is applied before data transfer. To
ensure the stability of the transmission in wireless networks, a
“transmit-acknowledge-require-retransmit” mechanism is
implemented on the application layer of Internet protocol in this
study.
