“…In MC, physicallayer network coding was not directly applied until 2016. Ghazani et al [263] for the first time used different molecule types to implement the XOR operator on the MC physical layer, and this use of different molecule types implements the physical-layer network coding. PNC in MC has to date mainly been examined in the timing scheme of half-duplex network coding, analogous to Table 9.…”

“…To solve the open challenge from [273], Ghazani et al [263] assign the molecule types X 1 and X 2 to the transceivers T 1 and T 2 , respectively. Molecule types X 1 and X 2 can react with each other through an irreversible reaction:…”

“…The implementation of a physical-layer XOR through chemical reactions represents a simple implementation of the XOR operator. By means of reaction-based schemes on the physical layer, the error probability in two-way relay MC is reduced, and the complexity is reduced since no XOR gate (implemented in electronics) is required at the relay [263].…”

“…Physical-layer network coding has been further examined by Farahnak et al [264], [274]. Analogous to [263], the network coding in [264] is implemented on the physical layer by executing an XOR operation inside the medium through chemical reactions. First, comparing the simulated Bit Error Probability (BEP) for a varied number of released molecules without considering the ISI, Farahnak et al [264] demonstrate a significant BEP decrease for physical-layer network coding compared to SNC.…”

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.

“…However, in MC, the transmitted signals cannot be negated naturally. M. F. Ghazani et al utilize the molecular reaction to cancel out the signals in [65], where another network coding scheme parallel to the PNC is presented with the ligand-receptor binding process. Specifically, different types of molecules are used at transmitters respectively and can react with each others, where the reaction rate is much more rapid than the molecule binding rate to the relay node.…”

Molecular communication (MC) is a kind of communication technology based on biochemical molecules for internet of bio-nano things, in which the biochemical molecule is used as the information carrier for the interconnection of nano-devices. In this paper, the basic principle of diffusion based MC and the corresponding key technologies are comprehensively surveyed. In particular, the stateof-the-art achievements relative to the diffusion based MC are discussed and compared, including the system model, the system performance analysis with key influencing factors, the information coding and modulation techniques. Meanwhile, the multi-hop nano-network based on the diffusion MC is presented as well. Additionally, given the extensiveness of the research area, open issues and challenges are presented to spur future investigations, in which the involvement of channel model, information theory, self-organizing nano-network, and biochemical applications are put forward.
