基于扩散的分子通信(DMC)被认为是实现健康应用的纳米网络。受人体内球状实体的启发，生物圈内扩散通道的建模受到启发。这种生物环境中的边界条件被认为是齐次边界条件(HBC)，它可以简单地模拟跨越生物屏障的分子过程，例如载体介导的跨血管壁运输和跨细胞转运。在这封信中，我们用HBC模拟了球面环境中任意位置的点源发射机和透明接收机之间的扩散通信信道。为此，在傅里叶域中解析地导出了浓度格林函数(CGF)。基于所导出的CGF来计算在接收器处接收的信号的统计以获得分析结果。分析结果用基于粒子的模拟(PBS)得到了准确的证实。还根据差错概率检查了简单的开关键控调制方案的性能。
Diffusion-based molecular communication (DMC) is envisioned to realize nanonetworks for health applications. Inspired by sphere-like entities in the body, modeling diffusion channel in the biological sphere is motivated. The boundary condition in such biological environments is considered as homogeneous boundary conditions (HBC) that can simply model the molecular processes over biological barriers, e.g., carrier-mediated transport and transcytosis over the blood vessel walls. In this letter, we model the diffusive communication channel between a point source transmitter and a transparent receiver arbitrarily located inside a spherical environment with HBC. To this end, the concentration Green’s function (CGF) is analytically derived in the Fourier domain. Statistics of the signal received at the receiver is computed based on the derived CGF to obtain the analytical results. The analytical results are accurately confirmed with particle-based simulation (PBS). The performance of a simple on-off keying modulation scheme is also examined in terms of error probability.
