Adaptive parameter control for physical wireless parameter conversion sensor network (PHY-C SN) according to feature of sensing information

We have proposed a physical wireless parameter conversion sensor network (PHY-C SN). In PHY-C SN, each sensor node converts its sensing information into subcarrier number of orthogonal frequency division multiplexing (OFDM) signals. Although information gathering in a short time can be realized by PHY-C SN, the accuracy of frequency mapping depends on the available number of subcarriers. In this paper, we propose an adaptive parameter setting method for PHY-C SN to realize efficient utilization of spectrum resource with high accurate information gathering. Simulation results show that the proposed method can gather sensing information effectively with utilizing the limited number of OFDM subcarriers.
