Abstract After a disaster has occurred, it is extremely difficult to confirm the safety of victims in an environment in which the communication infrastructure has been destroyed. For this reason, Delay Tolerant Networking (DTN), which makes communication possible even in environments which do not have adequate communication infrastructure, is being actively researched. Moreover, a relaying technology called message ferrying, which utilizes Unmanned Aerial Vehicles (UAVs), has been attracting attention as a means of mediating between sites that are not connected for communication during a disaster, thus facilitating the exchange of data between them. In order to improve the performance of message ferrying, the efficient movement of UAVs is necessary to ensure that safety information of more victims can be recovered in a limited time during disaster. In this study, evaluation experiments utilizing actual UAVs are conducted, UAV movement conditions are examined in light of the results of the experiments, and the ideal movement conditions of UAVs are described, with the overall objective of clarifying the necessary conditions for efficient movement of UAVs.
