Ad-hoc network for transmitting packets to plural target regions and packet transmission method thereof
First Claim
1. An ad-hoc network comprising:
- a relay node which receives a packet, comprising first location information of a first target region including at least one node and second location information of a second target region including at least one node, separates the packet based on the location information to form a first packet containing the first location information and a second packet containing the second location information, and forwards the first packet to the first target region and the second packet to the second target region; and
a source node which generates the packet comprising the first location information and the second location information, and transmits the packet to the relay node.

Abstract
A wireless ad-hoc network for transmitting packets to target regions, and a packet transmission method thereof, are provided. The ad-hoc network includes at least one relay node for receiving a packet containing location information of at least two target regions each including at least one node, separating the received packet by the location information, forming a new packet for each instance of the location information separated from the received packet, and forwarding the new packets to corresponding target regions; and a source node for generating the packet containing the location information and transmitting the packet to the relay node. The present invention can reduce the packet transmission overhead, the packet transmission delay, and the power required for the packet transmission. Therefore, the packets can be delivered to the target regions in an efficient manner.

9. A packet transmission method in an ad-hoc network that includes a source node transmitting a packet to at least two target regions each having at least one node, the method comprising:
-
generating the packet including location information of the at least two target regions each having the at least one node, and forwarding the packet to a relay node that corresponds to a Fermat'"'"'s point; and
receiving the packet at the relay node, and separating the packet by the location information to form a first packet containing first location information and a second packet containing second location information, and multicasting the first and second packets to the corresponding target regions. - View Dependent Claims (10, 11, 12, 13, 14, 15, 16)
