Systems and methods for monitoring a sensor network are described. The system includes multiple sensors and an upstream device, and the sensors are paired in turn as transmitting and receiving sensors. The sensors collecting signal strength data for each sensor pair corresponding to beacons transmitted and received by the sensors. The upstream device generates an aggregate fingerprint based on the signal strength data, generates a zone fingerprint for each zone based on the aggregate fingerprint, and determines a wireless communication performance of the sensor network based on the zone fingerprints. The aggregate fingerprint includes a signal strength value for each sensor pair. Each zone fingerprint includes the signal strength value for each sensor pair of the corresponding zone. A sensor network configuration is changed for one or more zones based on the wireless communication performance of the sensor network.

The disclosed systems, structures, and methods are directed to a digital watermarking system comprising: a data separator configured to receive a digital data file and segregate the digital data file into a message component and a data component, in which the message component includes a message, and the data component includes a data file; a message pipeline configured to process the message; a data pipeline configured to process the data file; a watermark pipeline configured to embed the processed message file onto the processed data file; and an inverse process pipeline configured to inverse the process applied by the data pipeline while processing the data file and generate a watermarked data file.
