Wireless sensor node for autonomous monitoring and alerts in remote environments
First Claim
1. A personal alert and tracking system comprising one or more nodes, wherein each of the one or more nodes comprises:
- (a) a first radio transceiver chip operating at a first frequency range and a second radio transceiver chip operating in a second frequency range, wherein;
(1) the first radio transceiver chip and the second radio transceiver chip enable the node to operate as either a mobile sensor node or a relay base station node;
(2) the second radio transceiver chip provides a relay link between the one or more nodes;
(b) a power amplifier that increases a line-of-sight communication between the one or more nodes;
(c) one or more sensors for providing sensor information, wherein the one or more sensors comprise;
(1) a global positioning system (GPS) module for providing a location;
(2) a temperature sensor for determining a temperature; and
(3) an accelerometer for triggering an alert condition;
(d) a first display for displaying alert information;
(e) embedded software configured to;
(1) capture and process the sensor information;
(2) provide a multi-hop packet routing protocol to relay the sensor information to a command center;
(3) receive alert information from the command center; and
(4) display the alert information on the display.

Abstract
A method, apparatus, system, and computer program products provides personal alert and tracking capabilities using one or more nodes. Each node includes radio transceiver chips operating at different frequency ranges, a power amplifier, sensors, a display, and embedded software. The chips enable the node to operate as either a mobile sensor node or a relay base station node while providing a long distance relay link between nodes. The power amplifier enables a line-of-sight communication between the one or more nodes. The sensors provide a GPS signal, temperature, and accelerometer information (used to trigger an alert condition). The embedded software captures and processes the sensor information, provides a multi-hop packet routing protocol to relay the sensor information to and receive alert information from a command center, and to display the alert information on the display.
