Performance of distributed detection system employing a set of geographically separated, deterministically deployed sensor nodes is investigated. It is assumed that the target signal power decays as a function of the distance from the target. For the case where the wireless channels have non-negligible error rates and sensor have nonzero fault rate, the system level detection performance is assessed. The authors provide new results on the detection performance of WSN in which a number of sensor nodes, transmit their binary decisions, regarding a binary hypothesis, to a fusion center. The fusion center is considered to employ the Neyman Pearson test on the decisions reported by local sensors.
