Abstract
A method and a system for synchronizing time information in an ad-hoc network are disclosed. According to the present invention, provided is a method for synchronizing time information in an ad-hoc network as a method by which a plurality of nodes included in an ad-hoc network synchronize a time, the method comprising the steps of: transmitting, by a first node, time information obtained by correcting an initial time using a first self-correcting value at an nth beacon interval, wherein the first self-correcting value is a self-correcting value or a local averaging value at an (n−1)th beacon interval; and correcting, by a second node which has received the time information from the first node at the nth beacon interval, time information by calculating a second self-correcting value and a local average value, wherein the first self-correcting value is either the self-correcting value or the local averaging value calculated at the (n−1)th beacon interval, and the local averaging value of the second node is an averaging value of time information of one or more neighboring nodes of the second node.
