Method and device for setting up route path

A device for setting up a route path, comprising:

• one or more processors, one or more memories, and a communication bus configured to couple the one or more processors and the one or more memories;
• wherein
• the one or more memories store one or more instructions, and when executed by the one or more processors, the instructions cause the one or more processors to:
• establish a neighbor list;
• wherein, the neighbor list comprises neighbor nodes of the node and position information of the neighbor nodes;
• in response to receiving a routing request (RREQ) message from a previous hop node, record a source Internet Protocol (IP) address of a source node contained in the RREQ message as a destination IP address in a routing table established in the node;
• record the previous hop node as a next hop node corresponding to the destination IP address in the routing table;
• select a pre-determined number of nodes from the neighbor list as next hop nodes of the RREQ message according to the position information of the neighbor nodes;
• and
• send the RREQ message to the next hop nodes.
