Abstract: PURPOSE: A routing method in a local wireless network and a method for assigning a network address are provided to receive an address from an access request node according to address use from an adjacent node, thereby flexibly coping with geographical arrangement of a node in network configuration. CONSTITUTION: If there is a connection request from new node A, node 58825 checks allocatable residual addresses(S10,S11). If there are not allocatable residual addresses, the node 58825 transmits an AB_REQ(Address Borrowing request message) to an adjacent node(S13). Node 58825 selects an address to borrow from at least one AB RSP(Address Borrowing response message)(S15). Node 58825 transmits an AB ACK(Address Borrowing Acknowledgement message) about address borrowing to a node(S16).
