Abstract
A method for anticipating the loss of connectivity between a mobile device and a wireless short-range access point among a plurality of such wireless access points, this method comprising the following steps: —collecting a plurality of paths corresponding to the mobile device movements within the coverage areas of the access points to which the mobile device was successively associated without loss of connectivity, each path comprising a root access point at which a connectivity is originated and a dead-end access point at which the connectivity is lost; —detecting the current access point to which the mobile device is currently associated; —identifying the paths comprising the current access point; —computing the risks of losing the connectivity when following each of the identified paths from the current access point to the root access point or to the dead-end access point of each of the identified paths.
