UAV route constructing methods have been researched based on an ad-hoc networks protocol, OLSR, composed by smart meter radio devices. We established the method which construct the most optimal route for UAV travel in terms of travel distance and safety avoiding densely populated area. In this research, in order to eliminate the risk of UAVs collision due to overlapping routes of multiple UAVs navigating simultaneously, we propose a method of locking links so that the link used for a UAV constructing route cannot be used for other UAVs. We also propose link hierarchization in the air to solve the link shortage caused by locking links. We evaluate effectiveness and characteristics of the proposed methods by computer simulation.
