20080205312 | METHOD AND DEVICE FOR ESTABLISHING A SECURE ROUTE IN A WIRELESS NETWORK - A method for establishing a secure route in a wireless network as provided improves network efficiency. According to one aspect, the method includes receiving at a first node in the wireless network a route request message from a second node, where the second node and the first node have not been mutually authenticated. The route request message is then forwarded from the first node to a third node. A route reply message is then received at the first node from the third node. The first node is then mutually authenticated with the second node in response to receiving the route reply message at the first node. | 08-28-2008 |

20090296674 | METHOD AND APPARATUS FOR DENSITY DETERMINATIOIN IN A WIRELESS COMMUNICATION NETWORK - Each node in a wireless communication network adds information in hello messages wherein the information comprises the number of hello messages received at the node from a plurality of nodes. Also, the nodes are configured to determine the node density based on additional information extracted from the received hello messages. For example, a first node in the wireless communication network receives a hello message from a second node, wherein the hello message comprises additional information indicating at least a number of hello messages received by the second node from a plurality of nodes in the wireless communication network. The first node extracts the additional information from the received hello message and based on the extracted additional information, the first node determines at least one channel performance metric. Based on the at least one channel performance metric the first node determines density of neighboring nodes in the wireless communication network. | 12-03-2009 |

20130127596 | METHOD AND APPARATUS FOR DETERMINING A LOCATION OF AN ITEM ATTACHED TO A RADIO FREQUENCY IDENTIFICATION TAG - A server in communications with two or more Radio Frequency Identification (RFID) readers receives information obtained by the two or more RFID readers within a coverage area. The received information is associated with the at least one item tag. The server assigns a predefined number of votes for the at least one item tag to fixed objects on which items attached to item tags are located. The predefined number of votes assigned to each fixed object is based in part on the received information. The server also calculates votes assigned to the fixed objects and determines the location of the at least one item tag to be a fixed object whose votes meet a predefined criterion. | 05-23-2013 |
20140084060 | RFID-BASED INVENTORY MONITORING SYSTEMS AND METHODS WITH SELF-ADJUSTING OPERATIONAL PARAMETERS - An inventory monitoring controller maintains information reflecting a current inventory of articles based on radio frequency identification (RFID) tag identifying information received from one or more RFID tag readers in the context of inventory polling operations. In an embodiment, the controller also adjusts an operational parameter (e.g., a missing article detection threshold or a variable polling parameter) based on an analysis of the RFID tag identifying information. For example, a variable polling parameter may be adjusted in response to an occurrence of a triggering event (e.g., an inventory change indicated by the RFID tag identifying information or an occurrence of a temporal event), and a missing article detection threshold may be adjusted based on historical information relating to the detection of (or failure to detect) a particular RFID tag. | 03-27-2014 |
