Abstract

Provided are an apparatus and method for asset tracking based on a ubiquitous sensor network (USN) using a motion sensing. The apparatus may include: a motion sensing manager to receive motion sensing information from a sensor; a filtering processor to filter the motion sensing information based on a filtering parameter and to determine whether a motion occurs based on the filtered motion sensing information; and a location information update (LU) manager to perform LU depending on whether the motion occurs.

Claims

1. An apparatus for asset tracking based on a ubiquitous sensor network (USN) using a motion sensing, the apparatus comprising:

a motion sensing manager to receive motion sensing information from a sensor;

a filtering processor to filter the motion sensing information based on a filtering parameter and to determine whether a motion occurs based on the filtered motion sensing information; and

a location information update (LU) manager to perform LU depending on whether the motion occurs.

2. The apparatus of claim 1, wherein the filtering parameter comprises at least one of a motion filtering time, a time interval to check the motion sensing information, and a threshold value.

3. The apparatus of claim 1, wherein the LU manager does not perform the LU when the filtered motion sensing information is less than a reference value, and performs the LU when the filtered motion sensing information is greater than or equal to the reference value.

4. The apparatus of claim 1, wherein the LU manager sets a polling interval for exchange of a polling message to be short when the motion sensing information is received, and performs the LU depending on whether the motion occurs.

5. The apparatus of claim 1, further comprising:

a filtering parameter processor to generate the filtering parameter according to a predetermined scheme and to provide the filtering processor with the generated filtering parameter.

6. The apparatus of claim 5, wherein the filtering parameter processor generates the filtering parameter based on accuracy of location information, a battery lifetime, a zone area where the asset tracking apparatus belongs, and a sensor condition sensed by the asset tracking apparatus.

7. An apparatus for asset tracking based on a USN using a motion sensing, the apparatus comprising:

a LU request receiver to receive a LU request from an asset node that performs a LU based on the motion sensing; and

an asset location information manager to update location information of the asset node based on the LU request and to mange the location information of the asset node,

wherein the asset node senses motion information, and determines whether the motion information requires the LU, based on a filtering parameter.

8. The apparatus of claim 7, further comprising:

a location information display manager to display the updated location information of the asset node via a display device.

9. A method for asset tracking based on a USN using a motion sensing, the method comprising:

determining whether motion sensing information is received;

determining whether a LU of an asset node is required based on the motion sensing information and a filtering parameter, when the motion sensing information is received; and

performing the LU of the asset node when it is determined the LU of the asset node is required.

10. The method of claim 9, wherein the determining whether the LU is required comprises:

setting a polling interval for exchange of a polling message to be short when the motion sensing information is received;

filtering the motion sensing information based on the filtering parameter; and

comparing the filtered motion sensing information with a reference value to determine whether the LU is required.

11. The method of claim 10, further comprising:

determining the LU is not required when the filtered motion sensing information is less than the reference value, and determining the LU is required when the filtered motion information is greater than or equal to the reference value.

12. The method of claim 9, wherein the filtering parameter comprises at least one of a motion filtering time, a time interval to check the motion sensing information, and a threshold value.

13. The method of claim 9, wherein the filtering parameter is determined based on accuracy of location information, a battery lifetime, a zone area where the asset node belongs, and a sensor condition sensed by the asset node.

14. A method for asset tracking based on a USN using a motion sensing, the method comprising:

receiving a LU request from an asset node that performs a LU based on the motion sensing; and

updating location information of the asset node based on the LU request to manage the location information of the asset node,

wherein the LU request is received when the motion information sensed at the asset node is greater than or equal to a reference value determined based on a filtering parameter.

15. The method of claim 14, further comprising:

displaying the updated location information of the asset node via a display device.
