Nanonetworks consist of nano‑sized devices capable of simple tasks, enabling applications such as advanced health monitoring and high‑performance distributed nano‑computing, and their plasmonic transceivers and antennas operating in the 0.1–10 THz band require tailored communication schemes. The paper develops a modulation and channel access scheme for nanonetworks in the Terahertz band. The authors propose a femtosecond‑pulse TS‑OOK modulation with asymmetric on‑off keying, evaluate its achievable information rate in single‑ and multi‑user scenarios, and develop a validated Terahertz channel model with stochastic noise and interference models. The results show that the modulation can support a very large number of nano‑devices simultaneously transmitting at multiple Gbps and up to Tbps, depending on modulation parameters and network conditions.
Nanonetworks consist of nano-sized communicating devices which are able to perform simple tasks at the nanoscale. Nanonetworks are the enabling technology of long-awaited applications such as advanced health monitoring systems or high-performance distributed nano-computing architectures. The peculiarities of novel plasmonic nano-transceivers and nano-antennas, which operate in the Terahertz Band (0.1-10 THz), require the development of tailored communication schemes for nanonetworks. In this paper, a modulation and channel access scheme for nanonetworks in the Terahertz Band is developed. The proposed technique is based on the transmission of one-hundred-femtosecond-long pulses by following an asymmetric On-Off Keying modulation Spread in Time (TS-OOK). The performance of TS-OOK is evaluated in terms of the achievable information rate in the single-user and the multi-user cases. An accurate Terahertz Band channel model, validated by COMSOL simulation, is used, and novel stochastic models for the molecular absorption noise in the Terahertz Band and for the multi-user interference in TS-OOK are developed. The results show that the proposed modulation can support a very large number of nano-devices simultaneously transmitting at multiple Gigabits-per-second and up to Terabits-per-second, depending on the modulation parameters and the network conditions.
