A METHOD FOR ALLOCATING FREQUENCY CHANNELS TO A PLURALITY OF NEIGHBORING ACCESS POINTS

摘要

In environments such as buildings in which access points are densely deployed, those access points influence each other. To provide a frequency channel allocation scheme in such densely populated environments information gathered by the access points are collected.;In such a situation, relying on a list of neighboring access points, background noise, communication medium business, the beacon messages received from access points as well as their associated RSSI, may lead to a frequency channel allocation scheme that may not significantly reduce the interference between access points.;The invention introduces an activity-based distance computed between at least two access points which represents a time overlap in a use of the communication medium.;This new metric offers a realistic representation of the influence access points have on each other. Indeed, an access point can only cause interference to another access point when they both use the communication medium at the same time.
