Wireless sensor network applications typically include various sensors (temperature, humidity, gas, etc.) and each sensor has different requirements of speed, noise, offset, and power consumption. In order to optimize the performance and allow long-time operation, reconfigurability is mostly desirable in the readout circuitry. In this paper, a reconfigurable time-domain comparator (RTDC) with low...
Wireless sensor networks (WSNs) have been widely studied in a lot of areas recently. In this paper, we present a method to examine the validity of distributed beamforming for source location in WSNs, by considering the effect of position errors, element failure, and environment noise, which often occur in practice. Computer simulation results show that even though the three errors exist, the direction...
