Nanonetworks: Next Frontier in Wireless Communications

Nanotechnology is paving the way toward the development of tinier devices on the scale of several nanometers. Communication among the nanodevices will contribute toward a nanonetwork, which can bring light to several groundbreaking applications. As the traditional electromagnetic (EM) communication approaches cannot be applied directly at the nanolevel, the research community has turned towards finding new solutions, one being nano-electromagnetic communication in the terahertz (THz) band. This paper investigates the fundamental issues of establishing a nanonetwork, mainly from the perspective of nano-EM communication in the THz band. We therefore aim to provide a short overview of the THz nano-EM communication, together with the contributions made by the authors in establishing the nanocommunication a reality.
