Systems and methods for using radio frequency signals and sensors to monitor environments

A sensor node, comprising:

• a memory for image data;
• an image capturing device to capture image data of loading zones and adjacent regions of a building;
• one or more processing units coupled to the image capturing device;
• and
• radio frequency (RF) circuitry to transmit RF communications to and receive RF communications from other wireless nodes within a wireless network architecture, wherein the one or more processing units of the sensor node are configured to execute instructions for processing the image data to monitor the loading zones and the adjacent regions within the building based on image data from at least two wireless nodes and the image data being used to determine for each loading zone whether a vehicle currently occupies the loading zone.

A method for monitoring a wireless network architecture, comprising:

• transmitting, with a plurality of sensor nodes each having a wireless device with a transmitter and a receiver, RF communications in the wireless network architecture to determine localization of the plurality of sensor nodes within the wireless network architecture;
• monitoring, with the plurality of sensor nodes each having an image capturing device, loading zones and adjacent regions within a building based on receiving image data from at least two sensor nodes;
• and
• determining for each loading zone whether a vehicle currently occupies the loading zone.
