Figure 2From: Minimum-Delay POIs Coverage in mobile wireless sensor networksAn example of POIs coverage for SSR. (a) There are two mobile sensors and eight POIs in the region. (b) POI H is added to the trajectory of M 2. (c) POI A is added to the trajectory of M 1. (d) The trajectories of M 1 and M 2 is constructed after the rest of the POIs are added one by one.Back to article page
