| Popis: | Recently, with the development of nano-technology, molecular communication has become a promising communication paradigm. In molecular communication via diffusion systems, nano-machines utilize the physical (concentration) or chemical (composition and structure) characteristics of message molecules to represent information. In order to restore the original information intended to be transmitted effectively at the receiver, the channel state information is essential, one of which is the relative position between the transmitter and the receiver. Previous studies focused mainly on one-dimensional distance estimation without considering the exact location of nano-machines. In this paper, four novel localization schemes based on trilateration method in a 2-D environment are proposed. The simulation results show that our proposed schemes can effectively locate the target nano-machine even under a low signal-to-noise ratio (SNR) and each scheme makes its own compromise between the accuracy and system complexity. |
