The reader device of claim 1, wherein the wireless devices are tags. 3. The reader device of claim 2, wherein the tags are radio frequency identification (RFID) tags. 4. The reader device of claim 2, wherein the reader device reads data stored in one or more of the tags using backscattering. 5. The reader device of claim 1, wherein the priority levels determined for the read requests correspond to the first network, the reader device further configured to receive a second network priority level from the second network for each of the plurality of read requests, wherein determining the priority level for each particular read request comprises determining the priority level based on the second network priority level received for the particular read request. 6. The reader device of claim 1, wherein determining the priority level comprises retrieving a priority level of the reader device. 7. The reader device of claim 6, wherein the priority level of the reader device is stored external to the reader device. 8. The reader device of claim 6, wherein the reader device comprises cache memory, wherein the priority level of the reader device is stored on the reader device cache memory. 9. The reader device of claim of claim 8 further configured to update the priority level stored on the reader device cache memory with the retrieved priority level when the retrieved priority level is different from the priority level stored on the reader device cache memory. 10. The reader device of claim 6, wherein the priority levels of the plurality of read requests are based on the retrieved priority level of the reader device. 11. The reader device of claim 1, wherein the reader device is further configured to retrieve data from a wireless device in the plurality of wireless devices in response to each read request, wherein determining the priority level comprises: for each particular read request, retrieving a priority level of the wireless device that is associated with the particular read request; anddetermining the priority level of the particular read request based on the priority level of the wireless device associated with the particular read request. 12. The reader device of claim 1, wherein the reader device is further configured to retrieve data from a wireless device in the plurality of wireless devices in response to each read request, wherein determining the priority level comprises: for each particular read request, retrieving a priority level of a wireless device that is associated with the particular read request and a priority level of the reader device; anddetermining the priority level for the particular read request based on the priority level of the wireless device and the priority level of the reader device. 13. The reader device of claim 1, wherein executing the plurality of read requests comprises retrieving, for each read request, data from one of the plurality of wireless devices. 14. The reader device of claim 13, wherein executing the plurality of read requests further comprises sending, for each read request, the retrieved data to the second network. 15. The reader device of claim 14, wherein the reader device is communicatively coupled to the second network via two communication channels, wherein the data retrieved for a first read request is sent to the second network through a first communication channel and the data retrieved for a second read request is sent to the second network through a second communication channel that is slower than the first communication channel based on the priority levels associated with the first and second read requests. 16. The reader device of claim 1, wherein the reader device is a first reader device in a plurality of reader devices, wherein each of the plurality of read requests is associated with a second network priority level corresponding to the second network, wherein the plurality of read requests are received from an access point of the second network that sends read requests to the plurality of reader devices in an order that is based on the second network priority levels associated with the read requests, wherein a first read request is sent to the first reader device before a second read request is sent to a second reader device in the plurality of reader devices when the second network priority level associated with the first read request is higher than the second network priority level associated with the second read request. 17. The reader device of claim 1, wherein each of the plurality of read requests is associated with a second network priority level corresponding to the second network, wherein the plurality of read requests are received from an access point of the second network that sends the plurality of read requests in an order that is based on the second network priority levels associated with the plurality of read requests, wherein a first read request is sent to the reader device before a second read request when the second network priority level associated with the first read request is higher than the second network priority level associated with the second read request. 18. The reader device of claim 1, wherein each of the plurality of read requests and each of a plurality of data items is associated with a second network priority level corresponding to the second network, wherein the plurality of data items and the plurality of read requests are received from an access point of the second network in an order that is based on the second network priority levels associated with the plurality of data items and the plurality of read requests, wherein the access point sends the plurality of read requests to the reader device before sending the plurality of data items to the reader device when the second network priority levels associated with the plurality of the read requests are higher than the second network priority levels associated with the plurality of data items. 19. The reader device of claim 1, wherein each of the plurality of read requests and each of a plurality of data items is associated with a second network priority level corresponding to the second network, wherein the second network comprises an access point that sends the plurality of data items to a plurality of receivers in the second network and sends the plurality of read requests to a set of reader devices in the first network, wherein the second network priority levels associated with the plurality of read requests are higher than the second network priority level associated with the plurality of data items, wherein the access point sends the plurality of read requests to the set of reader devices before sending the plurality of data items to the plurality of receivers. 20. 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 a 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 middleware and application software to provide quality of service (QoS). 21.
