Abstract:This paper addresses the issue of multiservice support in IEEE 802.16 or WiMAX networks. The capacity for supporting multiple service classes is indeed important for any access technology where bandwidth is limited, which is the case for IEEE 802.16. The standard currently proposes four traffic classes, and specifies that for uplink traffic, the first one (UGS) receives periodic grants whereas the other three are served via polling. Supporting two different scheduling mechanisms may have a significant impact o… Show more
