The algorithm is able to detectevents even if the measurements have poor signal-to-noise ratio,and its performance is independent of the characteristic of theinput signal. An efficient implementation of the algorithm isalso proposed, which allows the utilization of the algorithm onlow-end devices, e.g. in wireless sensor networking nodes. Theperformance of the algorithm has been tested and comparedto a conventional filter-based approach, in a vehicle detectorapplication.</p>
