A method for self routing of upsteam and downstream using beacon

摘要

An upsteam and downstream dynamic routing method using a beacon is provided to supply efficient dynamic routing by using beacon and join information of a MAC(Media Access Control) layer without using a route search packet. A node receives an address value from its parents node and shares address information with the parents node so that the node is joined with the parents node. The node determines whether a received data packet is broadcast(S201). When the data packet is not a packet to be broadcast, the node determines whether the node is a final destination node(S203). If the node is not a final destination node, the node transmits the data packet to the parents node based on the shared address information to set a routing route(S204).
