AI总结：
针对多全吸收接收器的扩散分子通信信道，论文提出受牛顿引力启发的重心解析模型，明确可将重心近似为接收器中心的条件，并用PBS验证其吸收分子数预测。
摘要：
在最近的一篇论文中已经表明，为了对具有多个全吸收（FA）接收器的扩散分子通信（MC）信道进行建模，从其他接收器的角度来看，这些接收器可以被解释为负粒子源。重心点被引入作为放置这些负源的最佳位置。该重心由撞击每个FA接收器表面的分子的空间平均值得到。本文推导了一个表达式，用于刻画具有多个FA接收器的扩散MC信道中重心的位置。在本工作中，受牛顿万有引力定律启发，找到了一个描述该重心的解析模型，并将结果与基于粒子的仿真（PBS）数据进行了比较。由于重心取决于发射器与接收器之间的距离以及观测时间，文中讨论了可以假定重心位于接收器中心的条件。这一假设简化了对任何包含多个FA接收器的扩散MC系统的进一步建模。所得重心位置被用于信道模型中，以计算吸收分子的累积数量，并且已在多种场景下通过PBS数据得到验证。
英文摘要：
In a recent paper it has been shown that to model a diffusive molecular communication (MC) channel with multiple fully absorbing (FA) receivers, these can be interpreted as sources of negative particles from the other receivers' perspective. The barycenter point is introduced as the best position where to place the negative sources. The barycenter is obtained from the spatial mean of the molecules impinging on the surface of each FA receiver. This paper derives an expression that captures the position of the barycenter in a diffusive MC channel with multiple FA receivers. In this work, an analytical model inspired by Newton's law of gravitation is found to describe the barycenter, and the result is compared with particle-based simulation (PBS) data. Since the barycenter depends on the distance between the transmitter and receiver and the observation time, the condition that the barycenter can be assumed to be at the center of the receiver is discussed. This assumption simplifies further modeling of any diffusive MC system containing multiple FA receivers. The resulting position of the barycenter is used in channel models to calculate the cumulative number of absorbed molecules and it has been verified with PBS data in a variety of scenarios.
