1. An identification and location network system comprising two or more nodes, with at least one programmable, location marking and processing, movable tag node, and at least one programmable fixed position node (FPN) for communication with the tag node, for the location, identification and monitoring of said tag node relative to the FPN;

  • said nodes each comprising an integrated circuit with programmable microprocessor means, a unique identification number, transceiver means for receiving and sending information, and memory storage means, and wherein each node further comprises means for direct inter-node communication and means for decision making capable of making decisions by itself, which do not require a central system processor for operation;

    the tag node further comprising an integral power source and means for communication with an FPN or other tag node with or without interrogation; and

    said FPN'"'"'s and tag nodes comprising interface means for interfacing with human or object input and output, wherein said integrated circuit comprises at least three independent microprocessors which share common memory means and control circuitry but with separate sets of registers, wherein a first microprocessor comprises a communication CPU adapted to provide media access control and communication between the nodes and includes linkage to the transceiver means for receiving and transmitting information.
