Outline of Final Research Achievements

Implantable medical devices have rapidly developed for realizing nanoscale bionanomachines and drug delivery systems. However, wireless communication based on electromagnetic waves is difficult to apply to nanomachines because their sizes of the transmit/receive antenna are determined by the wavelength. In this study, we focused on diffusive molecular communication technology, which has a potential feature to be applied to bionanomachines. This study investigated the feasibility to improve the reliability and throughput characteristics by introducing environmental parameter estimation and MIMO transmission.

Academic Significance and Societal Importance of the Research Achievements

これまでの拡散型分子通信の研究では理論解析による数学モデルの導出や通信方式においても限定的な検討に留まっていた。本研究は現実的な分子通信の環境下での通信特性の導出を目的に有限要素法による分子の拡散現象の解析を実施し、理想環境との差異を定量的に求め、その点において学術的意義がある。加えて、高度な無線通信技術であるMIMO伝送を分子通信への適用可能性を示し、高度な分子通信の実現に向けて寄与し、社会的意義を持つ研究成果をとなっている。
