Dynamic methods and systems for monitoring an environment. The methods and systems adopt functional nodes with at least one context node and one or more application nodes. The application nodes include at least one of a processing application node, a notifying application node, and/or an action application node. Input data of the environment are analyzed and detected. Representative data are extracted and compared with a group of comparative data by calculating a deviation between the representative data and the most similar comparative data. The notifying application node may send an alarm as a function of the deviation detected as above. An environment monitoring network is formed as a function of the functional nodes. The environment monitoring network is topologically variable as a function of i) the environment to be monitored, ii) the functions of the functional nodes and iii) the deviation detected. Monitoring occurs as a function of the topology of the implemented environment monitoring network.
