Abstract

Ultra wideband impulse radio (UWB-IR) technology has been defined in the IEEE 802.15.4a standard for location and ranging applications. In this paper, UWB-IR sensors are considered in wireless sensor networks (WSNs) with two different IEEE 802.15.4a based signalling; (i) binary pulse position modulation (BPPM) and (ii) combined BPPM/binary phase shift keying (BPPM/BPSK) modulation, for the detection of primary users. In addition to the modulation effects, the effects of each sensor´s false alarm and misdetection performances and the effect of signal-to-noise ratio (SNR) of the sensor-fusion center link have been investigated. For practical implementation of the WSN, some suggestions have been provided.
