Abstract

See full text

The application concerns interference mitigation in a CSMA/CA system (e.g. WLAN/WIFI); a distinction is made between two kinds of interference, namely “noise” and “congestion/collision”; a measure of congestion is determined as follows: if packets are queued waiting for transmission, a timer is started and the clear channel assessment (CCA) function is initiated. Periodically a check is made to determine whether a channel is available and when a channel becomes available the first queued packet is transmitted and the timer is stopped. The value recorded by the timer is used to indicate a measure of congestion.
