Method for transmitting FATIM in mobile ad hoc network and medium access control protocol layer module therefor
First Claim
1. A method for transmitting a flooding ad hoc traffic indication message (FATIM) in a power save mode having a beacon interval that is divided into an ad hoc traffic indication message (ATIM) window and a next data transmission window, in a mobile ad hoc network (MANET) including a plurality of nodes, comprising the steps of:
- when a first node of the plurality of nodes has data to be forwarded to different nodes, forwarding, by the first node, a FATIM frame indicating that a network broadcast message will be sent to other nodes neighboring the first node during the ATIM window; and
determining whether a current ATIM window has expired by a second node, and if the ATIM window has not expired, forwarding, by the second node, the received FATIM frame from the first node to other nodes neighboring the second node for indicating that a network broadcast message will be sent to the other nodes neighboring the second node.

Abstract
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.

6. A system for transmitting a flooding ad hoc traffic indication message (FATIM) in a power save mode having a beacon interval that is divided into an ad hoc traffic indication message (ATIM) window and a next data transmission window, in a mobile ad hoc network (MANET) including a plurality of nodes, comprising:
-
a first node for forwarding a FATIM frame indicating that a network broadcast message will be sent to other nodes neighboring the first node during the ATIM window when data to be forwarded to the plurality of nodes is present, a second node for determining whether a current ATIM window has expired when the FATIM frame is received from at least one of the neighbor nodes, and if the ATIM window has not expired, forwarding the received FATIM frame to other nodes neighboring the second node. - View Dependent Claims (7, 8, 9, 10)
