OLSR-Based Route Construction Method that Locks the UAV in-Flight Link and Crossing Links

We have studied a method for constructing routes for Unmanned Aerial Vehicles (UAVs) using a multi-hop network of wireless devices installed in individual houses. To eliminate the risk of UAV collisions caused by overlapping routes when multiple UAVs are operating simultaneously, we propose a route-locking mechanism to prevent links in an established route from being reused in constructing routes for other UAVs. Additionally, we introduce a method to prevent the use of links that cross locked routes during the route construction process for other UAVs. We propose an OLSR-based route construction method that locks the links over which UAVs are flying and also locks the links that cross them. We evaluate its effectiveness through computer simulations.
