MULTI-CASTING DATA TRANSMITTING SYSTEM AND METHOD USING SITUATION INFORMATION IN WIRELESS AD-HOC NETWORK

摘要

The present invention relates to a multicast data transmission system and a data transmission method using location information in a wireless ad hoc network. The present invention relates to a method for transmitting data from a source node to a destination node in a wireless ad hoc network, wherein the source node acquires information of neighboring nodes and is located at least one hop from the source node. Selecting a node; The source node selecting at least one intermediate node located in the direction of the target node among the intermediate nodes as at least one relay node for data transmission based on the location information of each of the intermediate nodes and the location information of the destination node; Two steps; And transmitting, by the relay node, data received from the source node to the destination node. Provides a multicast data transmission system and a data transmission method using location information in a wireless ad hoc network comprising a.
