disconnection possibility between the first network node 11 and the second network node 12 fig2 is a schematic view of a second embodiment of the present invention this embodiment aims at solving the problem that a new wireless transmission route cannot be established between the first network node 11 and the second network node 12 merely depending on the third network node 13 this embodiment is different from the first embodiment in that the reinforcing coordinates include a first set of reinforcing coordinates and a second set of reinforcing coordinates the third network node 13 is notified to move to a position with the first set of reinforcing coordinates and the wireless network group further includes a movable fourth network node 21 and the fourth network node 21 is notified to move to another position with the second set of reinforcing coordinates when the fourth network node 21 arrives at the position with the second set of reinforcing coordinates the third network node 13 and the fourth network node 21 are connected is series to establish the alternative first wireless transmission route 15 between the first network node 11 and the second network node 12 fig3 a and 3b are respectively a flow chart and a schematic view of a method according to a third embodiment of.
