Abstract

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.

Claims

21-23. -23. (canceled)

24. A method for selective wireless communications by a wireless two-way radio frequency data communications device, comprising the steps of:

(a) storing, in memory of the wireless two-way radio frequency data communications device; and

(b) filtering, by the wireless two-way radio frequency data communications device, a wireless communication received by it for an identification of its common designation within the communication, and

(i) processing the communication if an identification of its common designation is found therein, and

(ii) not processing the communication if an identification of its common designation is not found therein;

(c) wherein the wireless two-way radio frequency data communications device comprises a data packet radio device.

25. The method of claim 24, wherein the wireless two-way radio frequency data communications device comprises a digital processor.

26. The method of claim 24, wherein the wireless two-way radio frequency data communications device comprises logic circuitry.

27. The method of claim 24, wherein the wireless two-way radio frequency data communications device comprise memory in which a profile of the wireless two-way radio frequency data communications device is stored, the profile comprising the common designation assigned to the wireless two-way radio frequency data communications device.

28. The method of claim 27, wherein the profile further comprises a unique identification of the wireless two-way radio frequency data communications device.

29. The method of claim 24, wherein a preamble of the communication is screened for the common designation.

30. The method of claim 24, wherein the wireless two-way radio frequency data communications device is attached to an asset to be tracked and wherein the common designation is a class designation that represents a common characteristic or behavior of the asset.
