大尺度分子通讯通道的流体动力学模拟
A Fluid Dynamics Approach to Channel Modeling in Macroscale Molecular Communication
摘要：
本文提出了一种基于流体动力学的通道建模新方法，该方法将液滴作为分子通信通道中的信息载体，而不是分子。该方法考虑了由液相中的液滴与气相中的空气分子的相互作用产生的两相流。两相流与接收器（RX）的信号重构（SR）相结合以提出信道模型。模型的SR部分量化了在其接收体积中感测的分子信号的准确性如何取决于RX的灵敏度响应和液滴的粘附/分离过程。采用实验数据验证了所提出的信道模型。
英文摘要：
In this paper, a novel fluid dynamics-based approach to channel modeling, which considers liquid droplets as information carriers instead of molecules in the molecular communication (MC) channel, is proposed for practical macroscale MC systems. This approach considers a two-phase flow which is generated by the interaction of droplets in liquid phase with air molecules in gas phase. Two-phase flow is combined with the signal reconstruction (SR) of the receiver (RX) to propose a channel model. The SR part of the model quantifies how the accuracy of the sensed molecular signal in its reception volume depends on the sensitivity response of the RX and the adhesion/detachment process of droplets. The proposed channel model is validated by employing experimental data.
