Title (EN) METHOD AND APPARATUS FOR ESTIMATING COLLISION PROBABILITY IN A WIRELESS NETWORK
(FR) PROCÉDÉ ET APPAREIL D'ESTIMATION DE LA PROBABILITÉ DE COLLISION DANS UN RÉSEAU SANS FIL
Abstract: front page image
(EN)A method for estimating packet collisions within a wireless network, comprising:for each transmit packet an Access Point (AP) of the network records statistics transmission information; based on this statistical information the AP computes: Total number of slot times generated during this transmission, n; Total number of deferrals, m; and Total number of unsuccessful transmissions, Qs; and using a sequence (m,n,Q) of statistics for each access category (AC), the AP computes the probability of collision for unsuccessful packets, p.
(FR)La présente invention concerne un procédé d'estimation des collisions de paquets dans un réseau sans fil, comprenant : pour chaque paquet transmis un point d'accès (AP, Access Point) des informations de transmissions statistiques du réseau ; à partir de ces informations statistiques, le AP calcule : le nombre total d'intervalles de temps générés durant cette transmission, n ; le nombre total de reports, m ; et le nombre total de transmissions non réussies, Qs ; et grâce à une séquence (m, n, Q) de statistiques pour chaque catégorie d'accès (AC, Access category), le AP calcule la probabilité de collision pour des paquets échoués, p.
