Controle de Admissão e Reserva de Recursos em Redes Móveis utilizando Previsão de Séries Temporais

Kelvin L. DiasStênio F. L. FernandesDjamel F. H. Sadok

This paper proposes a novel call admission control (CAC) and reservation scheme for wireless mobile networks that avoids per-user reservation signalling. To this end, we propose the use of time series-based models for predicting handoff load. These methods are executed locally by each base-station or access router and forecast how much bandwidth should be reserved on a periodic time window basis. In addition, depending on the schemes settings, the prediction methods can grant an upper bound on handoff dropping probability even under very high load scenarios. The proposal is also improved with an adaptive approach to achieve a better bandwidth utilization.
