Abstract: A method and a device for detecting incidents in a local area network by way of an incident detection device, the incident detection device being connected to the local area network via a wide area network, a data collection agent collecting data describing the local area network. The device is able to detect various types of anomaly and receives messages from the collection agent, validates and aggregates data contained in each received message into groups of data, calculates a severity score for each group of data, for each type of anomaly and calculates a total severity score for each group of data, calculates a total criticality score from all of the total severity scores, and generates recommendation messages or corrective actions at least on the basis of the total criticality score.

Abstract: A method and an incident detection device in a local area network, an incident detection device being connected to the local area network by a wide area network, the local area network including a data conditioning and processing device, that: obtains, from the incident detection device, a processing repository for descriptive data from the connections between the stations and the nodes and descriptive data from the connections between the local area network nodes; aggregates the descriptive data from the connections between the stations and the nodes and the descriptive data from the connections between the nodes if the data processing repository includes information indicating that the data must be aggregated; calculates severity scores from the total severity scores according to the repository; and transfers aggregated data or severity scores to the incident detection device.

Abstract: A method for evaluating quality of radio links for a wireless body area network includes first and second wireless devices forming a body area network and configured to communicate with each other. One of the two wireless devices is mobile relative to the other, The method includes exploiting messages received by one of the wireless devices to measure instantaneous quality of a corresponding radio link and to estimate times during and between which a radio link is reliable, calculating an estimated times reliability indicator, and classifying the radio links as a function of the reliability indicator into at least first and second categories. One of these categories is a category relating to intermittently reliable radio links taking into account the mobility of the wireless devices of the body area network.
