Abstract:

Recently, many QoS architectures have been proposed to handle efficiently multi-service flows in IEEE 802.16 networks. However, these architectures have several weaknesses as they present some scalability issues and donpsilat consider the wireless nature of such networks (e.g. variable link capacity). Moreover, the proposed approaches fail in providing efficient admission control (AC) procedure to tackle congestions at both uplink and downlink channels. In this paper, we introduce new modules in both subscriber station (SS) and base station (BS), allowing more efficient handling of multi-service flows. We particularly focus on the design of a probabilistic and self-configuring AC algorithm, which prevents from uplink and downlink congestions while guaranteeing QoS to rtPS and nrtPS flows. Simulation results show that the proposed admission control protocol highly improves the management of underlying wireless resources, allowing therefore network operators to accept more QoS-enabled services.
