摘要: In order to provide seamless QoS-guaranteed services for IEEE 802.16e-based mobile BWA networks (MBWANs), this paper proposes a QoS-adaptive admission control with resource management which is undefined in 802.16e standard. Based on the different types of scheduling service standard, proposed scheme classifies them into connections according handoff-related parameters and uses bandwidth reservation strategies guarantee their connection-level QoS. Particularly, handoff connections, takes advantages dynamic guaranteed channel adaptive admit more new incoming while QoS existing not greatly degraded. theory, our can be modeled as M/M/m (n) queuing system, metrics, connection blocking probability (CBP) dropping (CDP) are derived, respectively. Finally, simulation results show that achieve better performance terms CBP CDP MBWANs.
