Dynamic time slot allocation for Multiuser OFDM/TDMA networks using effective bandwidth and βMWM network traffic modeling

Abstract

In this paper, we propose an adaptive allocation scheme which determines the number of time slots for each user in an OFDM/TDMA system using the Effective Bandwidth theory. For that purpose, we developed an algorithm to adaptively estimate the parameters of the MWM (Multifractal Wavelet Model) traffic model that allow us to calculate the effective bandwidth for the incoming traffic flows. We evaluate the performance of the proposed adaptive allocation scheme through simulations using real traffic traces.
