 note = {MQTT ベースの IoT センサー ネットワークのメッセージ集約方式を提案する．MQTT-SN ゲートウェイに特別なトピック名を持つ複数のメッセージを同一メッセージにまとめる集約機能を持たせた． 集約のための待ち時間の上限及び一つにまとめるメッセージ数の上限を設定できる．メッセージの集約により，MQTT ブローカとサブスクライバの負荷を軽減できる．, A message aggregation scheme for MQTT based IoT sensor network is proposed. On top of the connection aggregation scheme of the MQTT-SN Gateway, a novel message aggregation scheme is designed, where messages of special topic names are packed into a single MQTT message. Both the number of messages-based and the time-limit-based aggregations are implemented. The load of both the broker and the subscribers can be reduced by the message aggregation.},
