A routing method in a wireless network and a system thereof are provided to minimize the overall energy consumption and shorten routing and recovery time by reducing the amount of transmitted packets for routing and overheads for each node in a WPAN(Wireless Personal Area Network). A node, receiving an RREQ(Routing Request) packet, checks whether the RREQ packet has been repeatedly received through the flooding of another node(S500,S510). If not, the node confirms whether it is a cluster head(S520). If so, the node confirms whether it is a destination node(S530). If so, the node transmits an RREP(Routing Response) packet to the previous node(S540). In case the node is not the destination node, however, the node adds its own address to the header of the received RREQ packet and floods the RREQ packet(S550). |
