An Efficient Node Localization Approach with RSSI for Randomly Deployed Wireless Sensor Networks

Figure 4

Connectivity and localization effect ((a), (c), and (e) are the neighbor relationship of nodes for the beacon node’s number of 20, 30, and 40, resp. (b), (d), and (f) are the localization error for the beacon node’s number of 20, 30, and 40, resp. The communication radius is always 30 m).
