| Summary: | 碩士 === 逢甲大學 === 通訊工程所 === 95 === In the field of health care and bio-signal monitoring, a major challenge is how to support crews who have limited instruments and human resource to serve the increasing number of patients required long-term monitoring. A bio-signal monitoring device with wireless transmitting capability is an applicable solution. However, the current quality and reliability of these devices have not been very satisfactory due to various problems including size too big, uncomfortable feeling, spotty coverage and high power consuming. To cover part of these problems, Bluetooth and IEEE 802.11 are used in the medical domain. Bluetooth provides small size and wearable ability to bio-signal monitoring devices and 802.11 wireless modules provide larger coverage of signal transmitting. Both of these two technologies have the same merit, that is mobility; and the same shortcoming, that is limited power supply when operated by batteries. Our research aims various types of bio-signal which are monitored by ordered devices and passed through Bluetooth, and 802.11b modules in power saving management. We propose a pre-calculate mechanism to catch the specialized data flow of bio-signal packets. And by the flow behavior we design an algorithm to arrange the doze interval of 802.11 stations in order to saving more battery energy and promote longer utilization of wireless devices in medical applications.
