In this paper, we propose an adaptive Call Admission Control for IEEE 802.16 scheduled flows. As the WiMAX defined services aim to adapt the bandwidth grant to the data rate of accepted sessions, a powerful CAC that takes into account flows characteristics and their heterogeneities must be used. Our proposal aims to take advantage of the variability of traffics and to adapt the CAC according to the...
In this paper, we extend the results of our previous work, which mainly focuses on homogeneous services, and discuss the heterogeneous scenario. A cross-layer design is proposed for IEEE 802.16/WiMax networks, in which three modules are added: 1) an M-gated scheduler; 2) an admission controller; and 3) a parameter controller. The parameter setting for the M -gated scheduler is based on performance...
The grunt/request mechanism in IEEE 802.16e MAC provides different quality of service (QoS) for different service flows, wherein the call admission control (CAC) comparing the network resource available in the system with requirement of the QoS of the connection to decide if a connection can be admitted is an important stage to guarantee the QoS of each connection. Aiming at the current CAC's shortcoming...
