Method for automatically configuring network addresses in mobile multi-hop network
First Claim
1. A method for automatically configuring a network address of a first mobile node newly participating in a mobile multi-hop network implemented by the first mobile node, the method, comprising:
- (a) if the first mobile node belonging to a first network moves into and participates in a second network, detecting that the first mobile node has moved through transmission and reception of hello messages between the first mobile node and a second mobile node that belongs to the second network;
(b) securing a route from the first mobile node to a gateway of the second network and requesting network configuration information of the second network; and
(c) receiving an available network address allocated by the gateway and changing network configuration information of the first mobile node;
wherein (b) comprises;
receiving a first packet including information on the gateway of the second network from the second mobile node, wherein the information on the gateway includes a hop count to the gateway of the second network from the second mobile node; and
transmitting a second packet requesting the network configuration information of the second network to the second mobile node having the smallest hop count.

Abstract
The present invention relates to a method for automatically configuring network addresses of mobile nodes participating in a mobile multi-hop network. The method of the present invention includes a first step of, if a first mobile node belonging to a first network moves into and participates in a second network, detecting that the first mobile node has moved; a second step of securing a route from the first mobile node to a gateway of the second network and requesting network configuration information; and a third step of receiving an available network address allocated by the gateway and changing the network configuration information of the first mobile node.

13. A first mobile node newly participating in a mobile multi-hop network and receiving an allocated network address, comprising:
-
a detector operable to detect that the first mobile node has moved through transmission and reception of hello messages between the first mobile node and a second mobile node that belongs to a second network, when the first mobile node belonging to a first network moves into and participates in the second network; a second means for securing a route from the first mobile node to a gateway of the second network and requesting network configuration information of the second network; and a third means for receiving an available network address allocated by the gateway and changing network configuration information of the first mobile node; wherein the request for the network configuration information is made by receiving a first packet including information on the gateway of the second network from the second mobile node, wherein the information on the gateway includes a hop count to the gateway of the second network from the second mobile node, and transmitting a second packet requesting the network configuration information of the second network to the second mobile node having the smallest hop count. - View Dependent Claims (14, 15, 16, 17, 18, 19)
