%X The IEEE802.11e standard defines the Hybrid Coordination Function (HCF) which specifies the QoS algorithms in the MAC layer of the WLAN.HCCA is HCF Controlled Channel Access based on centralized polling mechanism and provides parameterized QoS.We addressed the efficient medium access control of variable bit rate (VBR) in HCCA,and proposed a novel scheduling algorithm,which can assign network resource based on associated flows using dynamical service intervals and transmission opportunity.The simulation resu...
