| Outline of Final Research Achievements |
In this research, we proposed a method to estimate positions of sensor nodes with higher-accuracy than GPS. The proposed method catches the LED light signal with a unique flashing pattern. This method also accurately estimates positions of nodes by measuring the direction of anchor nodes. We conducted the experiments where several sensor nodes are deployed on the field. In the proposed method, we confirmed that the estimation error of the sensor nodes that are near the anchor nodes is 10% less than GPS.
Finally, we tried to automatically estimate a field coverage by sensor nodes. However, we found a new problem to estimate positions of obstacles. We decided that we newly aim to solve this problem.
