First Claim
Patent Images
1. A method, comprising:
- receiving a message to direct to a destination node in a network;
examining a table to determine which adjacent radio frequency identification (RFID) reader to send the message to;
examining a list to determine a local RFID tag that the adjacent RFID reader is able to communicate with;
transmitting the message to the local RFID tag.

Abstract
A network of devices that use radio frequency identification (RFID) technology for communications may establish an ad hoc configuration for the network by identifying which RFID tags are shared by which RFID readers, and by creating and maintaining a distributed database of those configurations to facilitate the routing of communications between any tow nodes in the network.

7. A method, comprising:
-
receiving a message from a first radio frequency identification (RFID) reader, the message comprising a destination address for the message;
writing the message to a first queue if the destination address is a particular address;
writing the message to a second queue if the destination address is not the particular address;
receiving a poll from a second RFID reader; and
transmitting the message in the second queue to the second RFID reader responsive to said receiving the poll. - View Dependent Claims (8, 9, 10)
