摘要： Devices, such as tracking devices, cooperate with one another to establish the routing necessary for a relay network in which a device having power-efficient and data-reliable communication with an access portal, operates to relay messages from devices which do not have an acceptable communication path to and/or from the access portal. In one aspect of the present invention, a plurality of devices synchronously determine whether an acceptable communication path can be established between themselves and one or more access portals by measuring the signal strength of an access portal beacon. In another aspect of the present invention, one or more devices, which have determined that an acceptable communication path can be established between themselves and an access portal, transmit information regarding their availability to relay messages on behalf of devices which have determined that an acceptable communication path cannot be established between themselves and an access portal.

摘要： A method of determining a geographical location of an asset tracking device, includes searching, by the asset tracking device, for available location determination schemes at the geographical location, selecting one of the available location determination schemes, and determining coordinates of the geographical location using the selected location determination scheme. Some embodiments also include making a decision based, at least in part, upon the geographical location coordinates determined by using the selected location determination scheme. Some embodiments include transmitting a location message, the location message including the coordinates of the geographical location and an indication as to the selected location determination scheme.

摘要： Tracking devices having computational and communication resources receive information from a plurality of local devices, such as passive RFID tags, and collect and process the received information to determine one or more of when, where, and in what format to forward the collected information. The tracking devices typically include hardware resources for temporal- and location-awareness. In operation, these tracking devices may receive and respond to queries from remotely located tracking entities. In some embodiments, records of the communications between the devices and the remotely located tracking entities are made, and charges for the communication services are billed to the tracking entities that receive the communication services.
