The innovation process triggered by nanotechnologies is fostering the development of integrated devices with size ranging from one to few hundred of nanometers, very well suited for ICT, biomedical, industrial, and military applications. Here, the research activities include the characterization of different communication techniques for the nanoscale (including the exchange of electromagnetic waves in the Terahertz band and molecular diffusion), the design of energy-harvesting and low-complex communication protocols and network architectures, and the development of both analytical models and simulation tools to be used for evaluating the performance of nanoscale communication systems, based on reference standards (like IEEE 1906.1).
