Abstract

A mobile monitoring device and related systems and methods for monitoring a condition to which an object is exposed are disclosed. The monitoring device includes a sensor module for monitoring the condition and periodically producing sensor module data relating to the condition and a microcontroller. The microcontroller includes a sensor data component for receiving the sensor module data from the sensor module and a first transceiver component for receiving network manager data from a local network manager local to the monitoring device. The microcontroller further includes an associator component for comparing the network manager data with the sensor module data and, if the network manager data approximates the sensor module data, establishing an association with the local network manager.
