PROBLEM TO BE SOLVED: To provide a method for rebuilding a moving gateway access route for seamless route rebuilding or smooth data transfer. SOLUTION: This method relates to rebuilding a moving gateway access route. When a node adjacent to the gateway node starts data transmission to the moving gateway, it serves as a head node. This route rebuilding method comprises a step for broadcasting a head activate message to all adjacent nodes, a step for forwarding a head adjacent update message to the head node from all adjacent nodes receiving the head activate message and reporting their immediate states to the head node, and a step in which a node unadjacent to the gateway which attempt to transfer data to the moving gateway rebuilds a moving gateway access route via the head node.
