ββ¦We provide an intuition in Figure 2 that by identifying 3 disjoint representative sampling subsets from ππ€ π , we can increase the battery longevity by 3 times compared to the case of querying all sensors at any given time. It is therefore required to devise a system that can perform π) creation of a similarity graph of the sensors on the basis of the time-series data and, π) identification Sensor π Sensor π π 1 [4,5,5,5,4] π 6 [7,9,10,10,9] h π 2 [6,6,7,7,5] π 7 [9,9,9,11,7] π 3 [1,1,3,3,3] π 8 [0, 3, 3, 3, 0] π 4 [0, 0, 1, 1, 1] π 9 [1, 1, 1, 4, 1] π 5 [8,8,8,8,6 2: The distance between selected pair of sensors, π π and π π of ππ€ π by Fast DTW [51].β¦β
