The invention discloses a method for repairing fences based on a fence with fewest holes in hybrid sensor network, in the method, a part of holes are repaired by using a part of movable nodes, and a monitoring area is covered by a strong fence, so that the defense effect of the monitoring area can be achieved. Based on the graph theory, the fence with fewest holes is searched across the whole monitoring area and serves as a hole repairing object, so that the number of the movable nodes is reduced. A hole-movable node matching scheme that enables the shifting distance of the movable nodes to be shortest is searched by using match between the holes and the movable nodes, so that the consumed energy of the movable nodes in the moving process is reduced, and the survival time of the network is prolonged.
