Apparatus and method for setting multi-path
First Claim
Patent Images
1. A method for setting multiple paths between nodes including a source node, a relay node, and a destination node that receives a message from the source node via the relay node, the method comprising:
- receiving, at a node, previous hop address information;
determining whether the node that receives the previous hop address information is included in an insulating region, based on the previous hop address information; and
if a previous hop address included in the previous hop address information is not the same as the node'"'"'s address, setting the node as a wireless node in the insulating region,wherein the insulating region insulates a primary path between the source node and the destination node such that no other path is established in the insulating region.

Abstract
A method and apparatus is provided for setting multiple paths between wireless nodes of an ad-hoc network including a source node, a relay node and a destination node that receives a message from the source node via the relay node. The multi-path setting method and apparatus includes receiving previous hop address information, and determining whether a wireless node that receives the previous hop address information is included in an insulating region, based on the previous hop address information.

8. A multipath setting apparatus applied to a system including a source node, a relay node, and a destination node that receives a message from the source node via the relay node, the apparatus comprising:
-
a receiver for receiving previous hop address information; and a controller for determining whether the multipath setting apparatus is included in an insulating region, based on the previous hop address information, and if a previous hop address included in the previous hop address information is not the same as the node'"'"'s address, for setting the node as a wireless node in the insulating region, wherein the insulating region insulates a primary path between the source node and the destination node such that no other path is established in the insulating region. - View Dependent Claims (9, 10, 11, 12, 13, 14)

15. A non transitory computer-readable recording medium storing a program comprising:
-
a first set of instructions for receiving, at a node, previous hop address information; and a second set of instructions for determining whether the node that receives the previous hop address information is included in an insulating region, based on the previous hop address information, and if a previous hop address included in the previous hop address information is not the same as the node'"'"'s address, for setting the node as a wireless node in the insulating region, wherein the insulating region insulates a primary path between the source node and the destination node such that no other path is established in the insulating region.

16. A computer implemented method for setting a multi-path between wireless nodes comprising:
-
receiving a message from a source node via a relay node; receiving, at a node, a hop address of a previous node; determining whether the node that receives the previous hop address information is included in an insulating region, based on the previous hop address information; and if a previous hop address included in the previous hop address information is not the same as the node'"'"'s address, setting the node as a wireless node in the insulating region, wherein the insulating region insulates a primary path between the source node and the destination node such that no other path is established in the insulating region.
