Abstract :
WiMAX is currently one of the hottest technologies for broadband wireless access (BWA) systems which propose a wireless high-speed and high performance access system, with service differentiation for distinct classes of traffic and QoS requirements. IEEE802.16 standard specifies the PHY and MAC layers for BWA system and provides the flexibility of TDD and FDD allocation schemes. However, in spite of including the possibility of QoS support, the standard does not define how to schedule different types of traffic. In this paper, we present a modified scheme which is based on a reservation priority access control (RPAC) using FDD allocation approach, and we the behavior of this reservation scheme is analyzed and evaluated under balanced and unbalanced traffic conditions with the inclusion of variable priorities between stations.
