Time-based Relation/Analysis/Trajectory Operator for Multi-dimensional Data in IOT Environments
Jeong-Joon Kim · Solid State Technology · 2020
As technologies related to sensor network are currently emerging and the use of GeoSensor isincreasing along with the development of IoT technology, spatial query processing systems to efficientlyprocess spatial sensor data are being actively studied. However, existing spatial query processing systems donot support a spatial-temporal data type and a spatial-temporal operator for processing spatial-temporalsensor data. Therefore, they are inadequate for processing spatial-temporal sensor data like GeoSensor.Accordingly, this paper developed a spatial-temporal query processing operator, for efficient spatialtemporalquery processing of spatial-temporal sensor data in a sensor network.
