“…Importantly, Cheng et al [268] have investigated network coding for a mobile MC model, i.e., a communication system consisting of a mobile source nanomachines, a mobile relay nanomachine, and a mobile sink (destination) nanomachine. Aside from the Cheng et al [268] study on network coding and the Qiu et al [220] study on ISI-mitigating positionaldistance codes in a mobile DBMC nanonetwork, there have only been few studies on other (non-coding) aspects of mobile DBMC nanonetworks, e.g., studies on power control and adaptive detection [289], [290]. Generally, investigations of all types of coding (source, channel, and network coding) for mobile nanomachines are of critical importance, as the nanomachines for a myriad of Internet of Bio-Nano Things applications, e.g., in-vessel nanomachines for intra-body communication, are mobile.…”

Diffusion-based molecular nanonetworks exploit the diffusion of molecules, e.g., in free space or in blood vessels, for the purpose of communication. This article comprehensively surveys coding approaches for communication in diffusion-based molecular nanonetworks. In particular, all three main purposes of coding for communication, namely source coding, channel coding, and network coding, are covered. We organize the survey of the channel coding approaches according to the different channel codes, including linear block codes, convolutional codes, and inter-symbol interference (ISI) mitigation codes. The network coding studies are categorized into duplex network coding, physical-layer network coding, multi-hop nanonetwork coding, performance improvements of network-coded nanosystems, and network coding in mobile nanonetworks. We also present a comprehensive set of future research directions for the still nascent area of coding for diffusion-based molecular nanonetworks; specifically, we outline research imperatives for each of the three main coding purposes, i.e., for source, channel, and network coding, as well as for overarching research goals.

“…Therefore, the TX S has to estimate the distance (r SP ) [18], [19] in a practical implementation [20]. Also, the TX S has to store the values of u S [r SP ; k], 1 ≤ k ≤ l − 1 at any time-slot l. At large l (i.e., steady state), u S [r SP ; l] may become constant with time l.…”

Molecular communication often involves coexisting links where certain links may have priority over others. In this work, we consider a system in three-dimensional (3-D) space with two coexisting communication links, each between a point transmitter and fully-absorbing spherical receiver (FAR), where the one link (termed primary) has priority over the second link (termed secondary). The system implements the underlay cognitive-communication strategy for the co-existence of both links, which use the same type of molecules for information transfer. Mutual influence of FARs existing in the same communication medium results in competition for capturing the information-carrying molecules. In this work, first, we derive an approximate hitting probability equation for a diffusion-limited molecular communication system with two spherical FARs of different sizes considering the effect of molecular degradation. The derived equation is then used for the performance analysis of primary and secondary links in a cognitive molecular communication scenario. We show that the simple transmit control strategy at the secondary transmitter can improve the performance of the overall system. We study the influence of molecular degradation and decision threshold on the system performance. We also show that the systems parameters need to be carefully set to improve the performance of the system.

“…In [19], a diffusive mobile MC system is analyzed, where the initial distance at the beginning of the block is used as "outdated" channel state information. Power control can also be used as a mitigation strategy for both varying signal strength and ISI [20], [21]. In [20], to mitigate ISI in static MC, the authors adjust the number of transmitted molecules based on the number of residual molecules in the channel.…”

In this paper, we consider a mobile molecular communication (MC) system consisting of two mobile nanomachines, a transmitter and a receiver, propelled by a positive drift velocity and Brownian motion in a realistic blood-vessel-type flow regime. Considering the nonlinear movement of the nanomachines, an extended Kalman filter is employed to estimate the distance from the transmitter. Furthermore, based on the predicted distance, to keep the number of received molecules for bit 1 at a stable level, we employ power control on the number of transmitted molecules based on the distance between the transmitter and the receiver and the residual molecules in the channel from the previous transmission. Finally, the optimal detection threshold is obtained by minimizing the error probability. It is verified that a fixed optimal detection threshold can be effective for the power control scheme in the mobile MC. The bit error rate (BER) performance of our scheme is verified via simulation results.
