碩士 === 國立臺灣科技大學 === 電機工程系 === 104 === Bluetooth Low Energy, a wireless protocol tends to provide low power communication for battery-driven devices. A connection parameter is used by such protocol to extend the sleep time of BLE nodes. To provide the latency guarantee for sensing applications, the parameter is set in pessimistic and leads high energy consumption. In this paper, we present a power management framework for multiple BLE nodes having multiple applications with varied data rate and latency constraints. A connection parameter determination and a blocking-aware scheduler are proposed to enable the consideration of energy consumption and blocking. The proposed methodology is evaluated by extensive experiments and a real-life case study. The results indicate that the proposed algorithms registered 170% prolong in a lifetime performance compared with a simple pessimistic setting.
