Abstract

n recent years, the importance of wireless communications is increasing thanks to the numerous types of services support- ed by wireless devices, which allow the realization of thealways best connected vision. However, the dramatic boost toward miniaturization and nanoscale technologies requires rethink- ing of wireless communications on such a scale.In 1998, the Alliance for Telecommunications Industry Solutions (ATIS), one of the seven world leading ICT stan- dards development organizations, introduced a definition for “wire- less” [1]. This definition states that wireless is “descriptive of a network or terminal that uses electromagnetic waves (including RF, infrared, laser, visible light and acoustic energy) rather than wire conductors for telecommunications.”This definition is most relevant to the traditional vision of pure electromagnetic wireless communications that are embed- ded in various devices found within our environment. While the transformation from wired to wireless communication has improved connectivity for end users and spawned new research areas, the field as a whole is approaching a crossroad. The main reason for this is the emergence of miniature devices, in particular devices that are built from nano components, which has led to new challenges for the wireless communication paradigm.The field of nano communication has been developed as a new emerging area that will aim to address these challenges. This new field can be categorized into two main areas: • Electromagnetic nano communication (EM-nano) • Molecular communications EM-nano communication utilizes electromagnetic waves for communication, and requires addressing a number of new chal- lenges not covered by current wireless communication paradigms [2]. For example, unexplored frequency bands have to be utilized due to the nanoscale size of nanomachines and, thus, their antennas; also, nanonetworks require a large set of functions to be performed including addressing, information propagation, and access control, where traditional solutions may not be appli- cable due to the remarkable limitations in terms of computing and communication capabilities characterizing the nanoma- chines. Molecular communications, on the other hand, enable com- munication between nanomachines taking inspiration from natural biological mechanisms and requires a multidisciplinary perspec- tive [3–7]; this new area of research is basically a cutting edge research field that is emerging to be very promising, as witnessed by the increas- ing number of financed research projects [8, 9].
