abstract: |
This paper proposes a new interface model for crosslayer
designs using generalized fuzzy automata (GFA)
and fuzzy control. When using the proposed model, an
upper layer is reduced to an adaptive and cognitive
controller and the lower layers act as hierarchical
plants. In this paper, we utilize the model in wireless
LAN Quality of Service (QoS). The fuzzy controller
allocates bandwidths for different traffics, detects
saturation of performances, and criticizes satisfaction
of traffic specifications (TSPECs). The distributed
fuzzy controller adaptively tunes its fuzzy sets
according to both the TSPECs and the network states.
According to the realization theory and the
experiments, the adaptive QoS controller fulfills
TSPECs no matter what dynamics of the TSPECs and
the network environment are. |
