A method of forming ad hoc RSI hierarchical communication networks among pluralities of wireless transceivers includes assigning to each of the transceivers one or more common designations. A network organization routine of the transceivers operates to establish hierarchical networks based on the transceivers' common designations, resulting in a logical network organization that provides efficiencies for acquiring information from particular transceivers that share a common designation. Each transceiver's common designation is used by a digital processor of the transceiver to selectively receive data packets that are intended for receipt by transceivers sharing the particular common designation. Such a 'common designation' network reduces power consumption and signal interference thereby increasing battery life. Each transceiver may include a sensor interface a query handling routine in communication with a memory of the transceiver for serving as a dynamic distributed hierarchical database system of information such as, for example, sensor-derived information and time-sensitive information.

A method for determining a terrestrial location of an apparatus that is deployed in a generally known geographical region includes capturing, by the apparatus, an earthbound image of the sky from a terrestrial location at an identified time; communicating, by the apparatus, data representative of the captured earthbound image of the sky; and determining the terrestrial location of the apparatus based on the data communicated by the apparatus by comparing the captured earthbound image of the sky to a master mapping of the sky relative to the surface of the Earth.

A method for node communication in a mobile ad hoc network, which network includes a plurality of wireless mobile nodes and a plurality of wireless communication links connecting the nodes together, includes the steps of transmitting node condition information from a given mobile node using a signal; determining a node condition of the given mobile node, where the node condition includes priority of information to be transmitted by the given mobile node; and varying the signal by changing a transmission characteristic based upon changes in priority of information to be transmitted by the given mobile node.

A method for communicating to a recipient transceiver from a plurality of transceivers located within the broadcast range of the recipient transceiver includes: transmitting a communication at a first power level such that only a first group of transceivers receive the broadcast, the communication including a command causing each of the first group of transceivers not to respond to a subsequent broadcast; and subsequent thereto, transmitting a communication at a second power level greater than the first power level such that a second group of transceivers greater than and including the first group of transceivers receive the broadcast, but such that only a limited number of transceivers of the second group respond to the broadcast, the limited number of transceivers excluding the first group of transceivers. Each of the plurality of transceivers is associated with a respective sensor for acquiring data and transmitting the data to the recipient transceiver.

Communications within population of wireless transceivers based on common designation

A wireless transceiver includes a low power radio frequency (LPRF) component that powers down to conserve energy and powers up in response to a signal; and a second receiver that provides the signal in response to receipt of a radio frequency broadcast. The broadcast is targeted to activate particular transceivers by including, in the broadcasts, identifications such as class designations, in which case the transceivers power up and form networks. A transceiver may include one or more identifications and may include a unique identification of the transceiver itself. The LPRF component may be a Bluetooth radio, but the overall transceiver itself only draws about 10 to 15 &#x3bc;A while actively awaiting and screening for a targeted broadcast.

A plurality of wireless transceivers are associated with assets and each transceiver is assigned a class designation representative of an attribute, characteristic, relation, or behavior of its respective asset. Class based network formation routines are utilized to establish hierarchical networks based on asset classes, and the asset class is used by each transceiver to screen communications intended for receipt by transceivers of the same class. The overall wireless data communication network results in reduced power consumption and signal interference in asset-tracking applications. The transceivers may include a query handling routine for forming a dynamically distributed hierarchical database system. Furthermore, a recipient transceiver selectively receives communications from other local transceivers by transmitting at incrementally stronger power levels to successive groups of transceivers, and receiving reply transmissions only from a limited number of the transceivers that excludes those transceivers from which communications already are received.

Network formation in asset-tracking system based on asset class

A method of forming an ad hoc hierarchical communication network involves associating a plurality of wireless transceivers with articles, and assigning to each of the transceivers a class designation representative of a characteristic or behavior of the article with which the transceiver is associated. A network organization routine of the wireless transceivers operates to establish the hierarchical network based on the transceivers' class designations, resulting in a logical network organization that provides efficiencies for asset tracking. Each wireless transceiver's class designation is used by a digital processor of the wireless transceiver to selectively receive packets intended for receipt by transceivers of the same class. The class-based network reduces power consumption and signal interference, which increases battery life in the wireless transceivers. The wireless transceivers may include a query handling routine in communication with a memory of the transceiver for serving as a dynamic distributed hierarchical database system.
