Summary:
This paper presents the path loss prediction for wireless sensor applications in an orchard by using the uniform geometrical theory of diffraction (UTD) method. The tree in the orchard is modeled by using the proposed 3D UTD solution for an impedance cylinder. The wireless sensor network (WSN) is applied to improve the conventional harvesting process in a Thai commercial orchard. A wireless sensor node is attached on a raw fruit for example a durian on the durian tree. Therefore, the durian turns to be a part of the antenna. It is necessary to perform the source modeling. The GB expansion is used for the source modeling and this expansion can be applied to the UTD method effectively. The good comparison between the proposed 3D UTD solution including the effect of the wet good ground and the measurement result are obtained in the paper.
