“…In order to gain a fundamental understanding of the benefits of exploiting the spatial dimension in MC, in this paper, we study an MC system with a large number of transmission links, i.e., an asymptotic regime in terms of the number of TX and RX nodes. In contrast to [11]- [14],…”

“…However, this option has received less attention in the MC literature. Existing works exploit the spatial dimension for example in the context of multiple-input multiple-output (MIMO) MC systems [6]- [10] or for large-scale MC systems with many TXs by applying tools from three-dimensional (3-D) stochastic geometry [11]- [14]. A MIMO MC system comprises one TX and one RX, but the TX and the RX are connected to multiple spatially distributed release and reception sites, respectively.…”

“…The authors in [15] show that, for real-world base station locations, one relevant performance metric, namely the signal-to-interference-plus-noiseratio (SINR) experienced by the users, is upper bounded by the SINR of the users in an idealized grid network, and lower bounded by the SINR of the users in a random network. While existing research on multi-link MC systems is based on randomly positioned TXs and RXs [11]- [14], in this work, we assume an idealized, fixed, and predefined grid structure for the TXs and RXs. Therefore, the model considered in this paper provides a new perspective on multi-link MC systems.…”

We consider a multi-link diffusion-based molecular communication (MC) system where multiple spatially distributed transmitter (TX)-receiver (RX) pairs establish point-to-point communication links employing the same type of signaling molecules. To exploit the full potential of such a system, an indepth understanding of the interplay between the spatial user density and inter-user interference (IUI) and its impact on the system performance is needed. In this paper, we consider a three-dimensional unbounded domain with multiple spatially distributed point-to-point non-cooperative transmission links, where both the TXs and RXs are positioned on a regular fixed grid. For this setup, we first derive an analytical expression for the channel impulse responses (CIRs) between the TXs and RXs in the system. Then, we derive the maximum likelihood (ML) detector for the RXs and show that it reduces to a threshold-based detector. Moreover, we derive an analytical expression for the corresponding detection threshold which depends on the statistics of the desired signal, the statistics of the MC channel, and the statistics of the IUI. We also provide a low-complexity suboptimal decision threshold. Furthermore, we derive an analytical expression for the bit error rate and the achievable rate of a single transmission link.Finally, we propose a new performance metric, which we refer to as area rate efficiency (ARE), that captures the tradeoff between the transmission link density and the IUI. The ARE characterizes how efficiently the available TX and RX areas are used for information transmission and is expressed in bits per unit area. We show that there exists an optimal transmission link density for maximizing the ARE.The presented results reveal that the optimal link density depends on the number of molecules used for modulation and the value of the diffusion coefficient, while the impact of the chosen grid structure and the concentration of background noise molecules is negligible.

This paper investigates a spherical transmitter (TX) with a membrane covered by heterogeneous receptors of varying sizes and arbitrary locations for molecular communication (MC), where molecules are encapsulated within vesicles and released from the TX through membrane fusion. Assuming continuous vesicle generation at the TX and a transparent receiver (RX), we calculate the molecule release rate, the fraction of absorbed molecules at the TX, and the received signal at the RX. All obtained analytical expressions are functions of all receptors' locations and sizes, and are validated by particle-based simulations. Our numerical results indicate that evenly distributed receptors on the TX membrane can absorb more molecules than randomly distributed receptors or a single receptor. Furthermore, inspired by the autoreceptor functionality in synaptic communication, we incorporate a negative feedback mechanism (NFM) at the TX, such that molecule release stops after a certain period. We then derive the fraction of molecules that can be reused for the subsequent emissions when considering both NFM and molecule harvesting. Our numerical results demonstrate that incorporating NFM can reduce inter-symbol interference (ISI) while maintaining the same peak received signal as the case without NFM. Additionally, our results show that TXs incorporating both molecule harvesting and NFM can achieve a higher energy efficiency and lower error probability than TXs employing only molecule harvesting or neither functionality.
