| Outline of Final Research Achievements |
In this research, in order to establish a practical data retrieval system for the ecology/environmental observation field where it is difficult to deploy a network infrastructure, we have studied a new DTN technology utilizing air vehicles that support wireless communication and are equipped with auto-piloting function. First, based on the network coordinate system that maps communications nodes onto the multi-dimensional geometric space where the Euclidean distance expresses network latency between nodes, the prediction method of unknown communication quality of the moving vehicle has been developed. In addition, we have achieved a new data retrieval system by adding auto-piloting and wireless communication functions to air vehicles so as to obtain observation data from sensor nodes. Furthermore, in order to monitor operating status of moving vehicles on the field, a new operation management system has been developed.
