An improved method for monitoring a shipping container and responding to an environmental anomaly using a wireless node network having at least a plurality of ID nodes disposed within the shipping container and a command node mounted to and associated with the shipping container, each of the ID nodes having at least one environmental sensor and being associated with a respective one of a plurality of packages maintained within the shipping container, and wherein the command node being operative to communicate with each of the ID nodes and an external transceiver associated with a transit vehicle, the method comprising:
- generating, by the environmental sensor on each of the ID nodes, sensor data related to an environmental condition of the respective package associated with each of the ID nodes as the packages reside within the shipping container;
- broadcasting, by each of the ID nodes, the generated sensor data;
- detecting, by the command node, the sensor data broadcasted from the ID nodes;
- comparing, by the command node, the detected sensor data from each of the ID nodes and locally maintained context data related to each of the ID nodes, the context data including at least a plurality of environmental threshold conditions respectively corresponding to the packages;
- detecting, by the command node, the environmental anomaly for the shipping container when the comparison of the detected sensor data and the context data indicates an environmental condition for at least one of the packages exceeds its respective environmental threshold condition;
- generating, by the command node, a layered alert notification related to the environmental anomaly for the shipping container in response to detecting the environmental anomaly, wherein the layered alert notification identifies a targeted mediation recipient, identifies a targeted mediation action, and establishes a mediation response priority based upon the comparison of the received sensor data and the context data;
- and
- transmitting, by the command node, the layered alert notification to the transceiver unit to initiate a mediation response related to the targeted mediation action.
