Cubic metric (CM) is being recognized as a better alternative to determine the power de-rating of radio frequency power amplifiers (PAs) than peak-to-average power ratio (PAPR). However, in this letter our analysis shows that actually the CM is still inaccurate to predict the required PA power de-rating that satisfies the out-of-band radiation (OBR) requirement of a communication system. Further,...
The constrained capacity of wireless sensor nodes and harsh, unattended deploy environments make the data collected by sensor nodes usually unreliable. We have proposed a count-min sketch based anomaly detection scheme with the goal of detecting the anomaly data values in WSN. In this paper, we analyze the performance of the proposed scheme thoroughly. We show through experiments with real sensed...
