Smartphone Based Body Area Network System

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.
