10. A method for detecting presence of a drone, the method comprising:
receiving a set of samples of a radio-frequency (RF) signal from an RF receiver;
obtaining predetermined data of expected communication protocols used between the drone and a controller;
identifying one of the expected communication protocols as corresponding to the RF signal;
decoding the RF signal based on the identified one of the expected communication protocols; and
extracting a unique identifier of the drone based at least partially on the decoded RF signal,
wherein the method is performed by a plurality of nodes, each node comprising at least the RF receiver,
wherein the plurality of nodes is arranged in a decentralized configuration, and
wherein the plurality of nodes share their detection results and mitigate the drone either by themselves or cooperatively with other nodes within the plurality of nodes.
