Alternative communication paradigms

Participants : Antonio Costanzo, Valeria Loscri.

Nowadays, the always growing of connected objects and the strong demand to downsizing the devices in order to make the Internet of Things (IoT) paradigm more pervasive and ubiquitous, has motivated academic and industry people to investigate from one side mechanisms able to adapt quickly to the rapid external changes and to the quality of Services (QoS) parameters defined by the users and imposed by the adoption of new services and from another side, the investigation of portion of spectrum that have not been considered till this moment such as Terahertz band.

Bearing that in mind, we envisaged the possibility to leverage in a synergic way the Software Defined Radio (SDR) paradigm and the controlled mobility of mobiles wireless devices in order to adopt the most suitable modulation scheme and the best position with the objective to improve the network connectivity and coverage area [13].

On the other hand, spectrum scarcity and growing demand of nanocommunication systems have motivated researchers to investigation novel channel models in different portions of spectrum, namely in the THz band.

The fervent research activity in this direction is also motivated by the recent technological advances in new types of materials (e.g. graphene, novel metamaterials) presenting specific features suitable for this frequency spectrum and for the growing demand of downsizing antenna dimension.

In [15], we have investigated the chirality effect and Giant Optical Activity (GOA) and their impact when assuming different power allocation techniques.

On the other hand, when the nature of the matter and the interactions of specific particles and (quasi)particles such as phonons and photons are considered, there is a growing interest to investigate alternative communication paradigms based on these specific phenomena. In [14] we have performed an information theory analysis based on the generation of phonons elements when a source power as a cellphone is applied on biological tissue. The lesson learnt in this works is based on the consideration that where is heat transport it is possible to associate a communication paradigm. Follow this reasoning, in [50] we have revised the most recent advancement in terms of Visible Light Communication (VLC). Specifically, we have investigated Software Defined paradigm for VLC, in order to sketch out the main research directions for this new research domain.
