PURPOSE: A routing and a data transmission method based on an intersection layer in a wireless sensor network are provided to form a routing tree on a node synchronization stage. CONSTITUTION: A node of a network receives a sync packet(200). The corresponding node selects a node of the shortest routing length(202). In case two or more node with the most small routing length exists, the node checks routing cost information of a synchronous packet of the nodes(204). The corresponding node selects the node of the most small routing cost as own upper node(206). |
