The aim of the proposed project is to develop and analyse a novel model for macroscopic diffusion-based molecular communication based on a suspension of relays, i.e, a large number of relays in a medium, particularly a fluid. This concept shall for the first time enable molecular communication on a centimetre and metre scale without active material transport. By waiving active transport, distortions of the signal and hence intersymbol interference, as observed for example in laminar flow, shall be avoided. Nerve cells, with the triggering of an action potential and a subsequent refractory period and with the development of an excitation wave through the tissue, serve as a biological model for the relay cells. For an abstract model of this behaviour, suitable ranges and optimal values of the cell parameters with respect to data transmission shall be determined. An exact reproduction of the biological processes, in contrast, is not intended. The setup will be described as a stochastic model, where the stochasticity, in contrast to other approaches for diffusion in literature, lies in the randomly distributed positions of the relay cells, i.e., the sources of the overlapping diffusion processes. Furthermore, the influence of a fluctuation of the molecule concentration and a stochastic variation of the parameters of the relay cell shall be investigated. In contrast to previous approaches, a large number of relay cells shall be considered, which is necessary to use diffusion over macroscopic distances, and shall enable the transition from a model with discrete relays to a continuum model. In this way, the transmission of a symbol ’1’ is represented by an excitation wave in the medium. Thus, in addition to active transport and a pure diffusion, a third form of molecular data transmission shall be introduced. In addition to the analysis of the data transmission performance in relationship to the system parameters, options for an implementation of the model in a testbed shall be discussed.

拟议项目的目的是开发和分析一种新的模型，宏观扩散为基础的分子通信的基础上暂停继电器，即大量的继电器在介质中，特别是流体。这一概念将首次实现厘米和米级的分子通信，而无需活性材料传输。通过放弃主动传输，应避免信号的失真以及因此的码间干扰，例如在层流中观察到的。具有动作电位的触发和随后的不应期以及具有通过组织的激发波的发展的神经细胞充当中继细胞的生物模型。对于这种行为的抽象模型，应当确定关于数据传输的小区参数的合适范围和最佳值。相反，生物过程的精确再现并不是有意的。该设置将被描述为随机模型，其中与文献中的其他扩散方法相比，随机性在于中继单元的随机分布位置，即，重叠扩散过程的来源。此外，应研究分子浓度的波动和中继单元的参数的随机变化的影响。与以前的方法相比，应考虑大量的中继单元，这对于在宏观距离上使用扩散是必要的，并且应能够从具有离散中继的模型过渡到连续模型。以这种方式，符号“1”的传输由介质中的激励波表示。因此，除了主动传输和纯扩散之外，还应引入第三种形式的分子数据传输。除了分析与系统参数相关的数据传输性能外，还应讨论在试验台中实施模型的选项。
