Original Abstract Submitted
methods and systems for user presence detection using wireless technology. a computer-implemented method includes receiving one or more data signals from at least one wifi-node-to-access-point (ap) link or at least one wifi-node-to-node link, performing a signal pre-processing process on the one or more data signals to generate one or more pre-processed data signals, performing the signal pre-processing process including performing a uniform sampling process, a power normalization process, an anomaly sample removal process, and a filtering process, extracting one or more features using the one or more pre-processed data signals, and using the one or more features to determine whether a user is present in the home and identify a specific room in which the user is located.
