Summary:
In Physical Wireless Parameter Conversion Sensor Network(PhyC-SN) , sensor node selects the subcarrier of OFDM signal in accordance with the table between subcarrier and sensor information and then sends it to a fusion center (FC), where the table is referred to as the channel assignment table. Even if all the sensors access at the same time, the statistical tendency of all the sensor information can be recognized by analyzing the subcarrier component of the received signal and referring the channel assignment table. In addition, a signal separation method using the data continuity of sensing results has been proposed. However, if the sensor information among two or more sensor information are close to each other, the signal separation becomes difficult. In this paper, we propose the construction of channel assignment table for achieving both high-precision separation of sensor information and high-precision sensing information.
