In this paper, the author examines localization error will be minimal after adjusting the radio range of beacons' and error performance tradeoffs. Anchor based-range-free schema for Wireless Sensor Network. Localization algorithms are different in different network environments. His work is to find out an efficient localization algorithm for Wireless Sensor Network. The idea is to use anchor nodes for localization. Anchor nodes are special nodes that know their physical location. Anchor nodes are connected to GPS to find out their location. Wireless Sensor Nodes that do not know their location are known as unknown nodes. Unknown nodes communicate with anchor nodes. Anchor nodes use beacons and broadcast it within the range and make the proximity.
