1. A method for measuring a node location using a Media Access Control (MAC) layer in a coordinator node, comprising:
- requesting ranging measurement to a mobile node by broadcasting an MAC frame where ranging measurement start timing is indicated within the broadcasting MAC frame according to a ranging measurement request message for the mobile node transmitted from outside a piconet; and
receiving ranging measurement information measured in the mobile node as a response to the broadcasted MAC frame and broadcasting the MAC frame where ranging measurement end timing is indicated within the broadcasting MAC frame;
setting up a data communication zone having the maximum radius required for performing data communication according to a star topology and a ranging measurement zone having a radius required for performing ranging measurement between the mobile node and a reference node.
