Outline of Final Research Achievements |
There is a need for wireless networks that can exchange information accurately and quickly in order to integrate real and virtual spaces. The applicant has conducted this research with the aim of realizing a comfortable and safe space for humans by merging real space and flexible virtual space in an outdoor environment. We have developed a fundamental mechanism that contributes to low latency and high reliability of wireless networks by using interference cancellation techniques, and have shown that it improves the performance of wireless networks.

Academic Significance and Societal Importance of the Research Achievements |
既存のISMバンドを用いた無線センサネットワークによる実空間と仮想空間融合の取り組みでは,信頼性が低く遅延が大きいという問題があった.具体的には,これまでの無線ネットワークの研究では,干渉除去技術などの各種無線物理層技術が個別に単一ネットワークの大容量化のみを目指して検討されてきた.しかしながら,実際の環境では,容量の問題だけではなく,外来の干渉波による信頼性の低下や,遅延の増大が問題となる. 本研究では,コストの観点から携帯電話網を用いる事ができないISMバンドを用いた無線ネットワークにおいて,高信頼・低遅延性を実現する無線ネットワークの構築の一助となる結果をえた.
