Nano-networks are networks of devices inherently working and communicating at a scale ranging between one and hundreds of nanometers. The motivation behind these nano-networks is to enhance the complexity and range of operation of the system, as the nano-machines that will be part of these networks have significant limitations in terms of size and power consumption. Neither classical communication schemes nor protocols used in conventional networks are valid in this new scenario. For instance, synchronization between nodes is a feature commonly required to build a network architecture. In this paper, the authors propose Quorum Sensing as a valid tool to achieve synchronization in a cluster of nodes of a nano-network by means of molecular communication, and in a distributed manner.
