    Patent number: 8145445
    Abstract: A WSN-based context awareness engine applies spatial filtering to sensed data which is output from sensors included in a group to filter data in which an error does not occur, identifies a non-operated sensor, compares filtered data with at least one condition to determine a current state of a place corresponding to the group, and combines the determined current state and information regarding the group to generate a context-awareness result.
