Mecanismos para aliviar o problema de assimetria de retardos em Redes IEEE 802.11e

Juliana FreitagNelson FonsecaJosé Ferreira de Rezende

The IEEE 802.11e standard aims at supporting applications with QoS requirements. However, it does not define how this support should be given under specific network conditions. When the load of the downlink traffic is high, the queues in the access point build up faster than the ones in the stations, resulting in higher delays for the downlink traffic. This paper introduces a new control mechanism which dynamically tunes parameters of the 802.11e contention-based access method. The proposed mechanism aims at providing QoS as well as ameliorating the problem of delay asymmetry.
