Selective wake-up of data packet radio component using common designation communication
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.
