Outline of Final Research Achievements |
In this research project, we have considered wireless network tomography techniques considering spatio-temporal correlation properties in wireless links. We tackled two different network tomography problems: estimation of spatial distributions of received power for drone communication and Indoor RSS map estimation. In the former problem, we proposed a tensor-based wireless tomography scheme and a route control for drones for the wireless tomography scheme. In the latter problem, we proposed a Kalman filter-based wireless tomography using mobile measurement nodes. We validated both the schemes with simulation experiments.
