“…W k i is a doubly stochastic RV and as can be seen, ( 22) cannot be derived in a closed form. To make the analyzes tractable, one approach is to approximate the mean of W k i with a deterministic variable [35], [36]. We call this method as mean-value approximation.…”

In this paper, we propose a molecular communication system to localize an abnormality in a diffusion based medium. We consider a general setup to perform joint sensing, communication and localization. This setup consists of three types of devices, each for a different task: mobile sensors for navigation and molecule releasing (for communication), fusion centers (FC)s for sampling, amplifying and forwarding the signal, and a gateway for making decision or exchanging the information with an external device. The sensors move randomly in the environment to reach the abnormality. We consider both collaborative and non-collaborative sensors that simultaneously release their molecules to the FCs when the number of activated sensors or the moving time reach a certain threshold, respectively. The FCs amplify the received signal and forward it to the gateway for decision making using either an ideal or a noisy communication channel. A practical application of the proposed model is drug delivery in a tissue of human body, in order to guide the nanomachine bound drug to the exact location. The decision rules and probabilities of error are obtained for two considered sensors types in both ideal and noisy communication channels.

“…Motivated by similar studies, relaying is another scheme that has been under investigation in the last few years as an alternative way to improve reliability and overcome the high concentration dissipation of the messenger molecules. In Cheng et al, 17 an amplify‐and‐forward scheme is proposed which involves multiple relay nodes transferring a message from the transmitter to its intended receiver in a three‐dimensional environment. Similarly, in Cheng et al, 18 an energy efficiency analysis is performed for a multi‐hop network with mobile nodes.…”

Summary Chemotaxis has been studied as a means to improve communication performance in the promising field of biological nanonetworks. However, as of today, no protocols for reliable two‐way communications have been proposed in such networks. This work proposes a new protocol for switching between different chemotactic substances as a novel scheme to improve reliability of two‐way communications in biological nanonetworks. Multiple simulations, involving message exchange between stations and chemotactic release, were performed to evaluate the performance of the proposed strategies and achieve a deeper understanding of the behaviour of molecular communication nanonetworks. Furthermore, a novel message sending strategy utilising chemorepellent is presented, which does not involve the release of new molecules into the medium. Simulating chemotactic substance as individual molecules allowed for a more accurate modelling of the system in the boundaries of the chemotactic interface, bringing out the wave‐like behaviour of the latter. The results of the experiments indicate the effectiveness of the proposed controlled release strategy in improving message transmission quality. Furthermore, based on the findings of this work, we propose amendments of existing protocols that incorporate switching between chemotactic substances.

“…In the works of previous studies, 17,18 the authors investigate a relaying scheme for 3d multihop MC via diffusion where the communication parts use either different or the same type of molecules in each hop. Concerning the hop strategy, there are two different options, one with the decode and forward option [19][20][21] and one with the amplify and forward.…”

Diffusive biological nanonetworks have been established as a communication physical layer option and are envisaged to govern the development of future nanonetwork communications. Being the major communication paradigm in biological environments, it allows biological nanomachines to communicate through exchanging pulses of molecules in an aqueous medium being endogenous to these dimensions and following the requirements for biocompatibility and interoperability. The peculiarities of this nanoscale level, related mostly to the channel and the message carriers, hinder the performance of communication protocols. Therefore, in this work, parameters that affect the communication at the lowest level are being analyzed bringing new insights in the sector. Analyzing the major components that take part in the reception process, the dynamics of message transfer between nanonodes are revealed by a plethora of simulation scenarios. By entering into the equation the dynamics of chemotaxis, the behavior of such a system is scrutinized pertaining to the communication performance and stability. The proposed analysis revealed that unlike electromagnetic nanonetworks and due to the nature of the medium, there are factors that should be foreseen in the design of biological communication protocols. These significant deductions are supplementary to the established work, by shedding light on the special characteristics of biological communication entities and the way they affect the information exchange.
