Abstract

Embodiments of the present invention include systems and methods for providing Quality of service to RFID. In one embodiment the present invention includes a method of providing quality of service in an RFID network comprising storing RFID priority information corresponding to the RFID network, wherein the RFID network comprises one or more tags and one or more readers mapping the RFID priority information into priority information corresponding to a second network.

Claims

1. A reader device to provide quality of service in a radio frequency identification (RFID) first network comprising a set of tags, the reader device configured to:

receive data from a tag in the set of tags in response to an RFID request;

retrieve RFID priority information corresponding to said RFID first network;

determine an RFID priority level corresponding to the RFID first network for the RFID request based on the retrieved RFID priority information;

map the determined RFID priority level to a second network priority level corresponding to a second network communicatively coupled to the reader device, wherein the mapped second network priority level is different from the determined RFID priority level; and

send an RFID response comprising the data and the second network priority level to the second network.

2. The reader device of claim 1, wherein retrieving the RFID priority information comprises retrieving the RFID priority information from the tag.

3. The reader device of claim 1, wherein the tag is configured to store the RFID priority information, the reader device further configured to modify the RFID priority information that is stored on the tag.

4. The reader device of claim 3 further configured to transmit the modified RFID priority information on the tag to one or more other reader devices of the RFID first network.

5. The reader device of claim 1, wherein the RFID request is a first RFID request and the RFID priority level is a first RFID priority level, wherein the reader device is further configured to process the first RFID request (i) before a second RFID request having a second RFID priority level that is lower than the first RFID priority level and (ii) after a third RFID request having a third RFID priority level that is higher than the first RFID priority level.

6. The reader device of claim 1, wherein the second network comprises a set of access points, a set of base stations, a set of routers, and set of server controllers, wherein the reader device, the set of access points, the set base stations, the set of routers, and the set of server controllers comprise RFID middleware and application software to provide RFID quality of service (QoS).

7. The reader device of claim 6, wherein providing QoS comprises receiving a set of RFID requests in a first order and forwarding the RFID requests in a second different order based on the second network priority levels associated with the plurality of RFID requests.

8. The reader device of claim 6, wherein providing QoS comprises processing a plurality of RFID responses in an order based on second network priority levels associated with the plurality of RFID responses.

9. The reader device of claim 6, wherein providing RFID QoS comprises filtering duplicate and false tag reads by the reader device and one or more of said access points and base stations.

10. The reader device of claim 1, wherein the reader device comprises cache memory, wherein retrieving the RFID priority information comprises retrieving the RFID priority information stored on the reader device cache memory.

11. The reader device of claim 10 further configured to update the RFID priority information stored on the reader device cache memory with the retrieved RFID priority information when the retrieved RFID priority information is different from the RFID priority information stored on the reader device cache memory.

12. The reader device of claim 1, wherein the RFID priority information comprises a priority level of the tag and a priority level of the reader device, wherein retrieving the RFID priority information comprises retrieving the priority level of the tag and the priority level of the reader device.

13. The reader device of claim 12, wherein determining the RFID priority level comprises performing a calculation based on the priority level of the tag and the priority level of the reader device.

14. The reader device of claim 12, wherein the RFID priority level of the RFID request is a higher of the priority level of the tag and the priority level of the reader device.

15. The reader device of claim 12, wherein the RFID priority level of the RFID request is an average of the priority level of the tag and the priority level of the reader device.

16. The reader device of claim 1, wherein retrieving the RFID priority information comprises retrieving the RFID priority information stored on the second network.

17. The reader device of claim 16, wherein the RFID priority information stored on the second network is cached on an access point of the second network.

18. The reader device of claim 1, wherein the RFID priority information is stored on one or more reader devices of the RFID first network.

19. The reader device of claim 1, wherein the RFID priority information is based on attributes of the RFID first network.

20. The reader device of claim 19, wherein the attributes of the RFID first network include a location of the reader device or an application type that is supported by the reader device.

21. The reader device of claim 1, wherein the second network is one of a wired local area network, a wireless local area network, and a cellular network.

22. The reader device of claim 1, wherein mapping the RFID priority level to the second network priority level comprises converting the RFID priority level to a priority level of the second network by applying a mapping algorithm to the RFID priority level.

23. The reader device of claim 1, wherein the reader device is further configured to map the RFID priority level to the second network priority level based on the RFID priority level determined for the RFID request, a number of available RFID priority levels, and a number of available second network priority levels.
