We analyze the impact of the node density (increasing the number of nodes from 100 to 250 ordinary nodes) on the localization performance.
First, the localization results when the number of nodes is 100. As we can see, Figure (a) presents the movement of the anchor nodes. While Figure (b) shows the relation between the estimated and the actual locations of the ordinary nodes with an average localization error of 107.90 m. In contrast, Figure (c) presents the localization results for all anchors and ordinary nodes. |
