APPARATUS FOR DETERMINING A NUMBER OF DATA TRANSMISSIONS IN SENSOR NETWORK AND METHOD USING THE SAME

摘要

A device for determining the number of data transmission times in a sensor network and a method therefor are provided to reduce unnecessary power consumption by reducing the number of unessential data transmission times in a node, and to integrate data of nodes having sensing areas overlapping with user-interested areas. An interested area detector(220) detects an interested area on the basis of a user's query. An area decider(240) decides whether the interested area is overlapped with a sensing area. If the interested area is overlapped with the sensing area, an area calculator(260) calculates an overlapped degree. A transmission frequency determiner(280) determines the number of data transmission times according to the overlapped degree.
