The present invention discloses a locking route method based on next hop routing and source routing, the method is aimed at solving three big technical problems including mobility of nodes, scalability of network and limited energy in the wireless multi-hop network. By using a local broadcast, the locking route method can help the source node, effectively and adaptively track network topology changes resulted from moves of the nodes, find a substitution route, and lock a destination node. In the local broadcast, the propagation of a route control message is limited to only an original route and surrounding neighbor nodes, so that network cost is greatly reduced, and scalability of the network is enhanced, wherein a routing update along the direction from the destination node to the source node can find the substitution route in time according to link quality parameters and node operating parameters, thereby maintaining persistence of the communication, and prolonging useful life of the network as well. The locking route algorithm of the present invention is suitable for all wireless multi-hop networks comprising mobile ad hoc networks, wireless mesh networks and wireless sensor networks.
