          <datacite:description descriptionType="Other">本稿では自立発電による電力供給を想定し，Wi-Fi マルチホップ IoT ネットワークにおいて画像データを収集する通信方式を提案する．具体的には，IoT ネットワークは多数の sensor node と情報を収集する sink node1台から構成される．sensor node は一定時間ごとに起動して動作サイクルを実行する．動作サイクルには 4 つの時間的スロットから構成される．第 1 スロットでは sensor node は隣接 sensor node の探索や時刻同期を行う．第 2 スロットでは sensor node はセンサ値に加えて自身の座標情報やバッテリ残量などを sink node に送信する (push形式)．第 3 スロットでは，sink nodeは，sensor node から収集した情報に基づいて画像データ送信のスケジューリングと経路計算を行い，その結果を sensor node に通知する (SDN形式)．第 4 スロットでは sensor node は指定された時刻に指定された経路で画像情報をsink node に送信する (pull方式)．無線通信を模したエミュレータ上に提案方式を実装し，基本性能を測定した．その結果，バッテリ残量のばらつきを低減して sensor node をより長く生存させることが可能であることが分かった．</datacite:description>
          <datacite:description descriptionType="Other">This paper proposes a communication method for collecting image data in a Wi-Fi multi-hop IoT net work, assuming self-sustaining power supply. Specifically, the IoT network consists of a large number of sensor nodes and a single sink node that collects image data as well as sensor data. The sensor node wakes up at regular intervals and executes the operation cycle. The operation cycle consists of four temporal slots. In the first slot, each sensor node recognizes its adjacent sensor nodes and synchronizes its clock. In the second slot, in addition to the sensor data, each sensor nodes sends its status information such as remaining battery power (push manner). In the third slot, the sink node calculates scheduling and routes for image data transfer based on the information collected from the sensor nodes, and sends the result to the sensor nodes (SDN manner).  In the fourth slot, the requested sensor node sends image data along with the specified route at the specified start time (pull manner). The proposed method is implemented on an emulator that emulates wireless communication and measured the basic performance. As a result, it is confirmed that it is possible to reduce the variation of the remaining battery power and to make the sensor node survive longer.</datacite:description>
