Provided is a location measurement method of a mobile node using a predictive filter is provided for improving the location measurement accuracy of the mobile node. The location measurement method of a mobile node detects change of movement pattern of the mobile node, corrects weights of a location measurement period and a predictive filter depending on the change of movement pattern, and compensates a location of the mobile node using the corrected weights of the location measurement period and predictive filter.

Location measurement method based on predictive filter

A method for transmitting a flooding ad hoc traffic indication message (FATIM) in a power save mode whose beacon interval is divided into an ad hoc traffic indication message (ATIM) window and data transmission window subsequent to the ATIM window, in a mobile ad hoc network (MANET) constituted by a plurality of nodes. When one of the plurality of nodes has data to be forwarded to different nodes, a FATIM frame indicating that a network broadcast message will be sent to its neighbor nodes is forwarded during the ATIM window. If a current ATIM window has not expired, at least one different node of the plurality of nodes receiving the FATIM frame forwards the received FATIM frame to its neighbor nodes.
