CPC H04L 41/14 (2013.01) [H04L 41/12 (2013.01); H04L 41/22 (2013.01)] | 13 Claims |
1. A network diagnostic system for analyzing a wireless network comprising a plurality of access points, APs, implementing roaming by way of handover of wireless devices between APs, the network diagnostic system comprising:
an electronic processor; and
a non-transitory storage medium storing instructions readable and executable by the electronic processor to perform a network diagnostic method including:
extracting a global handover frequency, HF, graph from counts or frequencies of handover events over an analysis time interval in the wireless network wherein each handover event comprises a source AP from which a wireless device disconnects and a destination AP to which the wireless device connects;
constructing a HF network topology graph for the analysis time interval from the extracted global HF graph wherein the HF network topology graph has nodes representing at least a subset of the APs of the extracted handover events and edges connecting pairs of nodes with each edge having a weight representing a count or frequency of handover events between the APs represented by the pair of nodes connected by the edge; and
performing a network diagnostic or visualization task using the HF network topology graph.
