What is it about?
Home delivery by UAV is expected to become popular. In the future, many UAVs will be flying over our daily lives carrying packages, and collisions between UAVs or slowing or stopping to avoid collisions will be time and energy inefficient. We aim to create a collision-free airway using a multi-hop network of wireless devices installed in each house in advance, and have UAVs navigate along the airway.

Why is it important?
Unmanned Aerial Vehicle (UAV) route constructing methods have been researched using protocols for ad hoc networks composed by smart meter radio devices. In the previous study, we established the method which construct the most optimal route for UAV travel in terms of travel distance and safety based on OLSR. Every node was given information whether it was in a densely populated area or scattered residential 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 the route of other UAVs. In addition, we propose link hierarchization in the air to solve the link shortage caused by locking links.
Perspectives
This research result is a technology that can compute UAV routes autonomously and decentrally by applying the technology of a worldwide network, and has very high scalability in the node scale. This technology is a dream come true, enabling the flexible construction of airways in future cities where many UAVs fly across the sky, as seen in movies and other media.
