METHOD FOR LOCALIZATION BASED GROUP

摘要

PURPOSE: A group based measuring position method for enhancing accuracy measures the location of the unknown node through the hop count and distance information. The position measurement error of the unknown node due to the routing route of the unknown node is minimized. CONSTITUTION: The anchor floods beacon to the network(S101). Unknown nodes store the beacon signal of the minimum hop count about different anchor(S105). In unknown nodes, the anchor of the beacon having the most small hop count establish as its own group anchor(S106). Nodes locating in anchor use the calculation hop-distance of anchor(S102). Unknown nodes decide whether the group anchor transmitting one hop-distance table is its own group anchor or not(S107).
