Fig. 7From: Hybrid energy-efficient APTEEN protocol based on ant colony algorithm in wireless sensor networkThe 100-node network model of the WSN. The 100-node network model of WSN is shown in this figure. One hundred nodes are randomly distributed between the area of (x = 0, y = 0) and (x = 200, y = 125) with the sink node at (x = 75, y = 175)Back to article page
