Performance Evaluation of Wireless Body Area Network in u-Health Environment

The WBAN that can collect measured vital sign through sensors enables continuous monitoring for the elder and chronic disease. As smart devices become popular, the development of WBAN has been easier. We have optimized WBAN by control of sampling rate. The sampling rate presents as the number of data per second. It is important factor that determines resolution of waveform. Even high sampling rate cause decline of network performance. The smart device has multi threads such as Bluetooth thread and main thread. The Bluetooth thread collects vital sign from sensing node. The main thread performs processing for vital sign and computation for drawing waveform. We expect to contribute to developing of cloud computing system for u-Health environment.
