SEDCF: seasonal enhanced service differentiation for IEEE 802.11 wireless ad-hoc networks based on seasonal processes
Nabil Tabbane, Sami Tabbane, Ahmed Mehaoua · 2006
In this paper, we try to reduce the degree of QoS degradation in IEEE 802.11 wireless ad-hoc network while enhancing at the same time the estimation of the networks contention window. We shall present SEDCF: Seasonal Enhanced Service Differentiation methods for forecasting resources to meet the QoS requirements for real-time service support based on Seasonal processes. These processes provide no stationary models, that adequately represent the time Contention Window CW variations. The results obtained (in terms of throughputs and end-to-end delays) show that the SEDCF protocol, performs better than conventional EDCF.
