Resumo
This paper proposes adaptive resource allocation in multiuser wireless networks based on
OFDM. Two allocation schemes are proposed: for TDMA networks and LTE networks.
The resource allocation schemes that provide QoS are developed from the union of OFDM
wireless networks, the proposal of adaptive modeling of traffic flows and the proposal of
adaptive estimation of effective bandwidth. The performances of the proposed schemes
are verified through simulation. Concepts and studies on traffic modeling, multifractal
traffic modeling, theory of effective bandwidth, OFDM, are addressed in order to support
the understanding and development of the proposed schemes. An algorithm for adaptive
parameter estimation of the multifractal model bMWM is proposed, and studies to
estimate the effective bandwidth are presented. Some methods of estimating effective
bandwidth are proposed using traffic flow models.
