Outline of Final Research Achievements

I proposed a spectrum assignment algorithm to satisfy service-oriented communication quality in a heterogeneous environment such as ZigBee/Wi-Fi coexistent network. In addition, I also proposed a control platform to realize the algorithm.
The proposed method assumes variety of service types such as multimedia traffic with strict delay constraint, data traffic with reliable delivery, and so on. It does not consider averaged quality, but achieves the required criterion of each service.

Academic Significance and Societal Importance of the Research Achievements

無線通信の重要が高まり,周波数資源が逼迫する中で,適用領域の拡大が続くIoT(Internet of Things)の更なる発展には,周波数利用効率の更なる向上が必要不可欠である.本研究成果は,複数のIoTサービスが稼働する環境で,サービス毎に求められる通信品質の違いを考慮し,それらを満足させつつ利用効率を最大化する周波数割り当て手法を確立しており,IoTの持続可能な発展を実現するものである.
