New paradigms in wireless communication systems

This paper discusses what a new paradigm can be in wireless communication systems of the twenty-first century. First, it suggests two directions for the new paradigm; one is "micro- and nano-device communication system" which is the projected scenario considering that the entities in source and destination have been shrinking throughout the history of wireless communication systems. The second direction is "networked robot system", which emerges as a natural extension of mobile ad hoc networking where the networking is closely related to motion control of robots. Secondly, it shows two interesting research topics, "the new communication protocol design" and "signal processing", respectively, that arise in the wake of the fusion between the two directions in the novel communication paradigm. Finally, it considers a new science of wireless communications in the twenty-first century.
