This paper proposes a novel imperfect spherical transmitter (TX) model, namely the membrane fusion (MF)-based TX, that adopts MF between a vesicle and the TX membrane to release molecules encapsulated within the vesicle. For the MF-based TX, the molecule release probability and the fraction of molecules released from the TX membrane are derived. Incorporating molecular degradation and a fully-absorbing receiver (RX), the end-to-end molecule hitting probability at the RX is also derived. A simulation framework for the MF-based TX is proposed, where the released point on the TX membrane and the released time of each molecule are determined. Aided by the simulation framework, the derived analytical expressions are validated. Simulation results verify that a low MF probability or low vesicle mobility slows the release of molecules from the TX, extends time required to reach the peak release probability, and reduces the end-to-end molecule hitting probability at the RX.

用于分子通信系统的基于膜融合的发射机设计

本文提出了一种新的不完美球形发射器 (TX) 模型,即基于膜融合 (MF) 的 TX,它在囊泡和 TX 膜之间采用 MF 来释放封装在囊泡内的分子。对于基于 MF 的 TX,推导出分子释放概率和从 TX 膜释放的分子分数。结合分子降解和全吸收接收器 (RX),还可以推导出端到端分子在 RX 处的命中概率。提出了一种基于 MF 的 TX 模拟框架,其中确定了 TX 膜上的释放点和每个分子的释放时间。在仿真框架的辅助下,对导出的解析表达式进行了验证。模拟结果验证了低 MF 概率或低囊泡迁移率减慢了分子从 TX 的释放,
