A routing method and apparatus are provided. The routing method includes the following steps: sending a probe frame that carries an address of a destination node to a neighboring node(s); receiving a response message returned; selecting one neighboring node from the neighboring node(s) that returns the response message as a next-hop node to which data is sent. A neighboring node with a cost parameter which is lower than a cost parameter in a routing table of the destination node is selected as the next-hop node. In the routing method, when a routing node forwards data, the route is found in real time by broadcasting a probe frame, and data may be sent as long as any one of the neighboring nodes that may arrive at the destination node is in an active state, and thus a data transmission delay is shortened.
