Development of special smartphone-based Body Area Network: Energy requirements

In recent years, smart-devices became very popular among people of all ages around the world. Very important is especially their usage in health applications. Special Body Area Network (BAN) for the stress monitoring is currently being developed within the authors´ department. Android-based smartphone is employed as the main control unit of the sensor network built on the star architecture. Since the power consumption of the smart-phone as well as of the single sensor node is one of the key limitations of the network, special attention has to be given on it. In this article, energy requirements necessary for the data transmission among the network is analysed in detail. For this purpose, communication solution based on 2.4 GHz proprietary RF transceiver is implemented.
