Ad hoc network for transmitting packet to plural target reigon and packet transmitting method thereof

This transfer is capable of wireless ad-hoc network and a packet transmission method of the packet into a plurality of target areas are provided. The ad-hoc network includes at least one relay node that receives the at least one node, at least two are the packet including location information of the target area consisting of and splits the received packet for each location, flooding in the target area, and the location It generates a packet of information is included and a source node for transmission to the relay node. As a result, it is possible not only to reduce the packet transmission load, and a packet transfer delay to reduce the power consumed in the packet sent also to effectively transfer the packet into a plurality of target areas. Target area, Fermat point, relay node,
