Special Issue Information

Dear Colleagues,

The Terahertz (THz) (0.1-10 THz) electromagnetic (EM) and molecular nano communication have emerged as promising areas of research with the potential to revolutionize communication systems at the nanoscale. THz band, lying in the frequency range between microwaves and infrared light, enables high-speed, ultra-broadband EM communication with applications ranging from the software-defined metamaterials and Internet of Nano-Things (IoNT) to wireless networks on chip (WiNoC) and in-body communication. On the other hand, molecular nano communication explores the utilization of molecules as carriers for information exchange, enabling communication at the nanoscale targeting the biomedical domain with respect to Internet of Bio-Nanothings (IoBNT).

This Special Issue seeks original research papers, review articles, and case studies that address various aspects of terahertz electromagnetic and molecular nano communication. Prospective authors are invited to submit original, unpublished manuscripts on topics including, but not limited to, the following:

  • Terahertz electromagnetic wave generation, propagation, and detection for nano communication purposes;
  • Molecular nano communication models, protocols, and algorithms;
  • Hybrid approaches combining terahertz and molecular nano communication;
  • Terahertz and molecular nano communication for biomedical and healthcare applications;
  • Terahertz and molecular nano communication for Internet of Things (IoT) and smart systems;
  • Channel modeling, characterization, and performance analysis in terahertz and molecular nano communication;
  • Novel devices, materials, and technologies for terahertz and molecular nano communication;
  • Terahertz and molecular nano communication for nanoscale sensing and imaging;
  • Nanonetworking protocol stack, i.e., physical, link, network, transport, and application layers;
  • End-to-end nanonetwork architectures;
  • Security, privacy, and integrity in terahertz and molecular nano communication systems;
  • Standardization proposals and reviews.

Molecular communication (MC) represents a paradigm shift in communication technologies, extending beyond traditional electromagnetic methods by incorporating advances in nanotechnology, biotechnology, and communication theory. This innovative approach holds promise for groundbreaking applications in diverse fields such as medicine, military operations, and environmental monitoring. MC employs molecules to carry and transmit data. In concentration-encoded molecular communication (CEMC), information is represented through the concentration levels of the transmitted molecules. In this study, we introduce a novel method named time-hopping concentration-position shift keying (TH-CPSK), designed to facilitate multiple access within MC networks. The TH-CPSK method encodes information based on the position of the transmitted molecular concentration, significantly enhancing the accuracy of data transmission by reducing interference in MC channels. Numerical simulations reveal that an increase in the number of users adversely affects communication performance. Furthermore, our findings indicate that augmenting the number of hops improves communication performance at transmitter-receiver distances of 1 cm and 2 cm. Conversely, at a distance of 3 cm, performance degradation is observed, attributed to the increased complexity. Therefore, it is important to carefully select the number of hops considering the molecular channel’s characteristics. Overall, TH-CPSK can enhance the efficiency and reliability of CEMC systems, offering a significant step forward in the realization of MC’s potential applications. Full article
