Path planning for UAV harvesting information from dynamical wireless sensor nodes at sea
Ho, Tu Dac; Grøtli, Esten Ingar; Johansen, Tor Arne (Chapter, 2022)A system of several wireless sensor nodes and one unmanned aerial vehicle (UAV) is considered in this research. The nodes are only floating and drifting with the sea stream. The UAV will be operating as a data mule to ... -
PSO and Kalman Filter-Based Node Motion Prediction for Data Collection from Ocean Wireless Sensors Network with UAV
Ho, Tu Dac; Grøtli, Esten Ingar; Johansen, Tor Arne (Peer reviewed; Journal article, 2021)In this paper, we consider a wireless sensor network of nodes at the sea surface drifting due to wind and sea currents. In our scenario an Unmanned Aerial Vehicle (UAV) will be used to gather data from the sensor nodes. ...
