1. A system for monitoring a sensor network comprising:
sensor pairs of a plurality of sensors including a transmitting sensor and a receiving sensor for each sensor pair, each sensor of the plurality of sensors being assigned as the transmitting sensor in turn, the plurality of sensors collecting signal strength data for each sensor pair corresponding to beacons transmitted by each transmitting sensor and received by each receiving sensor; and
an upstream device communicating with the plurality of sensors, the upstream device generating an aggregate fingerprint based on the signal strength data, generating a zone fingerprint for each zone of a plurality of zones based on the aggregate fingerprint, and determining a wireless communication performance of the sensor network based on the zone fingerprints of the plurality of zones, each zone fingerprint including the signal strength value for each pair of transmitting and receiving sensors of the corresponding zone, and
wherein a sensor network configuration is changed for one or more zones of the plurality of zones based on the wireless communication performance of the sensor network.
