Bathtub-Shaped Failure Rate of Sensors for Distributed Detection and Fusion

Figure 1

A sensor deployment example. In sensor networks for distribution detection the local observations have to be quantized before being transmitted to the FC which is demanded to make the final decision about the target's presence. Area of the square region: 𝐴²; circle: the good sensors; square: the failed sensors which are bad and do not send their data to the FC; triangle: the failed sensors which still send their untrusted data to the FC; and star: the target.
