Default network topologies of simulation. (a) Net 1: Hierarchical Spanning Tree (HST) of 100 nodes deployed randomly. The sensing range is 25 m while the communication range is 50 m. The progress bar indicates the capacity of the battery (initially full). The sink node is 0. (b) Net 2: Hierarchical Spanning Tree (HST) of 138 nodes deployed using zigzag scheme [3]. The sensing range is 25 m and the communication range is 50 m. The progress bar indicates the battery capacity. The sink node is 56. (c) Net 3: Hierarchical Spanning Tree (HST) of 182 nodes deployed using grid scheme [4]. The sensing range is 25 m and the communication range is 50 m. The progress bar indicates the battery capacity. The sink node is 90. (d) Net 4: Hierarchical Spanning Tree (HST) of 181 nodes deployed using grid scheme [4]. The sensing range is 25 m and the communication range is 50 m. The progress bar indicates the battery capacity. The sink node is 140.
