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

1-30. -30. (canceled)

31. A method of providing quality of service for upstream data in a first RFID network comprising a set of tags and a set of readers, the first RFID network communicatively coupled to a second network, the method comprising:

at a reader, receiving data from a plurality of tags;

retrieving a reader priority level corresponding to the reader;

for each tag;

retrieving a tag priority level corresponding to the tag; and

combining the retrieved reader priority level and the retrieved tag priority level to calculate a priority level for the received data from the tag; and

sending, to the second network, the retrieved data from the plurality of tags based on the calculated priority level for the received data from each tag.

32. The method of claim 31, wherein combining the retrieved reader priority level and the retrieved tag priority level comprises:

selecting a function from a plurality of functions; and

utilizing the selected function to combine the reader and tag priority levels.

33. The method of claim 32, wherein the function is one of maximum, minimum, average, median, and sum of the tag priority and the reader priority.

34. The method of claim 32, wherein the function selects the reader priority level as the priority level when combining the reader and the tag priority levels.

35. The method of claim 32, wherein the function selects the tag priority level as the priority level when combining the reader and the tag priority levels.

36. The method of claim 31, wherein combining the retrieved reader priority level and the retrieved tag priority level comprises applying a first weight to the tag priority level and a second different weight to the reader priority level.

37. The method of claim 31, wherein the tag and reader priority levels are combined through an RFID application software within the RFID reader, wherein the RFID application selects one of a plurality of functions to combine the tag and reader priority levels.

38. The method of claim 31, wherein the reader priority level is based on an importance of data accessed by the reader, a time, or an application type that is supported by the reader.

39. The method of claim 31, wherein the reader priority level is based on a location of the reader.

40. The method of claim 39 further comprising:

updating the location of the reader via GPS; and

setting the reader priority level based on a set of pre-assigned location priorities.

41. A system of providing quality of service for upstream data, the system comprising:

an RFID first network; and

a second network communicatively coupled to the RFID first network;

the RFID first network comprising;

a set of tags; and

a set of readers, each reader configured to;

receive data from a plurality of tags;

retrieve a reader priority level corresponding to the reader;

retrieve, for each tag, a tag priority level corresponding to the tag;

combine, for each tag, the retrieved reader priority level and the retrieved tag priority level to calculate a priority level for the received data from the tag; and

send, to the second network, the retrieved data from the plurality of tags based on the calculated priority level for the received data from each tag.

42. The system of claim 41, wherein combining the retrieved reader priority level and the retrieved tag priority level comprises:

selecting a function from a plurality of functions; and

utilizing the selected function to combine the reader and tag priority levels.

43. The system of claim 42, wherein the function is one of maximum, minimum, average, median, and sum of the tag priority and the reader priority.

44. The system of claim 42, wherein the function selects the reader priority level as the priority level when combining the reader and the tag priority levels.

45. The system of claim 42, wherein the function selects the tag priority level as the priority level when combining the reader and the tag priority levels.

46. The system of claim 41, wherein combining the retrieved reader priority level and the retrieved tag priority level comprises applying a first weight to the tag priority level and a second different weight to the reader priority level.

47. The system of claim 41, wherein each reader further comprises an RFID application stored within the reader, wherein the tag and reader priority levels are combined through an RFID application software, wherein the RFID application selects one of a plurality of functions to combine the tag and reader priority levels.

48. The system of claim 41, wherein each reader priority level is based on an importance of data accessed by the reader, a time, or an application type that is supported by the reader.

49. The system of claim 41, wherein each reader priority level is based on a location of the reader.

50. The system of claim 49, wherein each reader is further configured to:

update the location of the reader via GPS; and

set the reader priority level based on a set of pre-assigned location priorities.
