12. 1. The Watcher Algorithm of Peak Count peak[11] peak[0] For count peak value, using Circle Queue Within 5 sec, count peak. Initially, fill all queues with peak[0]’s value. After that, within next 5 sec, count peak and fill an circle queue. Repeat 3 continuously. 3. peak[1] … peak[5] peak[2] peak[4] peak[3] peakCount = Σpeak[i] peak over pending threshold peak pending threshold • Hankuk University of Foreign Studies • Information & Communications Engineering
