Abstract

A mobile monitoring device for continual remote monitoring of a condition is provided. The device includes a sensor module for monitoring the condition and producing sensor module data relating to the condition. A first transceiver component receives network manager data from a local network manager and may transmit sensor module data to the network manager for remote monitoring by a server. An associator component compares the network manager data with the sensor module data. If they approximate each other, an association with the local network manager is established, during which geographical location data of the local network manager is included in the network manager data. The association is dissolved if the network manager data no longer approximates the sensor module data, after which an inertial navigation component incrementally estimates a geographical location of the monitoring device using the previously received geographical location data and subsequent sensor module inertial navigation data.

Claims
