          <datacite:description descriptionType="Other">スマートフォンの使用可能時間の短さが問題になっており，その原因の一つとして Wi-Fi の使用がある．最近では Social Networking Service (SNS) のように，データを受信するタイミングが不定期的なアプリケーションが増えており，その通信のために Wi-Fi を常に起動して電力を多く消費している．筆者らは，モバイル端末の消費電力の改善を目的として，電力消費の少ない Bluetooth Low Energy (BLE) を用いて必要なときにだけ Wi-Fi をウェイクアップさせることで，Wi-Fi の使用による消費電力の削減を行う方式を提案済みであり，アプリケーションによるプロトタイプの作成も既に行っている．今回，本方式を PC 上に実装し評価した結果，従来の省電力モード (PSM) と比較して，提案方式により消費電力を約 4 割削減できる可能性があることを確認した．</datacite:description>
          <datacite:description descriptionType="Other">The short lasting time per charge of smart phones is a concern to users, and one of the causes is the frequent use of the embedded Wi-Fi module. With the widespread of new applications like social networking service (SNS), the Wi-Fi module in a smartphone is kept awake because packets arrive at irregular timing, which is unpredictable. To reduce energy consumption, we had proposed a Wi-Fi wake-up control method by using a low power BLE module as a wake-up radio, which activates the powerhungry Wi-Fi module on demand. We also made a prototype system, which, however, has limited effect because of the constraint of Android API. In this paper, we implemented this method in the driver level, and evaluated its performance on a testbed PC. Experimental results confirm that the proposed method can reduce energy consumption of a Wi-Fi module by about 40%, compared with the conventional power-save mode (PSM).</datacite:description>
