Routing system for establishing optimal route in wireless personal area network (WPAN) and method thereof
First Claim
1. A routing method in a mobile communication system having a plurality of nodes including a destination node and a source node to establish a route to the destination node, the routing method establishing a route from the source node to the destination node with at least one node storing no routing table, and said routing method comprising:
- reviewing a route request message at one of said plurality of nodes;
storing information about a relaying node using information included in the received route request message, and sending the route request message to adjacent nodes; and
forwarding to said at least one node a reply message by using the stored information, in response to the received route request message.

Abstract
A system of routing and a routing method in a mobile communication system having a plurality of nodes including a destination node and a source node which intends to establish a route to the destination node wherein at least one node does not store a routing table. The method includes storing information on an intermediate node which relays a route request message using information included in the received route request message, and sending the route request message to neighbor nodes. A reply message in response to the received route request message is forwarded to the node which requests the route setup by using stored information.

7. A system of routing data in a mobile communication system having a plurality of nodes including a destination node and a source node to establish a route to the destination node, the system of routing using at least one node storing no routing table, comprising:
-
the source node generating a route request message and sending the generated route request message to an adjacent node; and
at least one intermediate node for storing information about a relaying node using information included in the received route request message, and requesting a route establishment with a reply message in response to the received route request message, using information stored in a routing table. - View Dependent Claims (8, 9, 10, 11, 12, 13)
