Abstract

A method for reducing a time period needed by a data gathering device to collect data from nodes of a wireless mesh communications network, communications between said data gathering device and said nodes being performed according to a spanning tree, is such that said data gathering device performs: transmitting requests in a first scheduling sequence for collecting said data; detecting a transmission issue on one wireless link; determining at least one route comprising said wireless link; modifying the first scheduling sequence to obtain a second scheduling sequence, by postponing at least one request addressed to at least one respective node present on the at least one determined route, and by putting forward at least one request addressed to at least one respective node present on at least one route distinct from said at least one determined route; and continuing transmitting requests according to the second scheduling sequence.
