1. A method comprising:
collecting path data including a plurality of paths from a plurality of messages of a plurality of devices;
determining positions of joints where two or more paths branch off based on the path data;
determining at least one path passing through two joints among the joints;
generating a path map based on node information including information about the at least one path and joint information; and
transmitting a first message including information on the path map,
wherein the joint information includes angle information and probability information for each of the joints, and
wherein the probability information for a joint is calculated using a total number of devices passing through the joint and the number of devices passing through each of the two or more paths branching off from the joint based on the path data.
