Patent ID: 8160838

Claim:
A method comprising: establishing communication with a plurality of networked environmental sensors deployed at sensor points in one of a plurality of pre-defined layers for a facility, each of the plurality of networked environmental sensors being a node in a wireless sensor network and configured to dynamically join the wireless sensor network, automatically discover neighbor nodes, and self-configure communication paths for routing messages between nodes of the wireless sensor-network; periodically obtaining measured environmental data values from each of the plurality of networked environmental sensors at the sensor points and routing the measured environmental data values in messages between nodes of the wireless sensor network; using the measured environmental data values at the sensor points to interpolate computed environmental data values at intermediate points in the facility, the intermediate points being between the sensor points; associating the measured environmental data values and the computed environmental data values with particular visual representations; and using the particular visual representations, the measured environmental data values and the computed environmental data values to generate a visualization of environmental conditions in the facility.
