We present a software framework for simulating the HCF Controlled Channel Access (HCCA) in an IEEE 802.11e system. The proposed approach allows for flexi-ble integration of different scheduling algorithms with the MAC. The 802.11e system consists of three modules: Classifier, HCCA Scheduler, MAC. We define a commu-nication interface exported by the MAC module to the HCCA Scheduler. A Scheduler module implementing the reference scheduler defined in the draft IEEE 802.11e document is also described. The software framework re-ported in this paper has been implemented using the Net-work Simulator 2 platform. A preliminary performance analysis of the reference scheduler is also reported.

Abstract
We present a software framework for simulating the HCF Controlled Channel Access (HCCA) in an IEEE 802.11e system. The proposed approach allows for flexi-ble integration of different scheduling algorithms with the MAC. The 802.11e system consists of three modules: Classifier, HCCA Scheduler, MAC. We define a commu-nication interface exported by the MAC module to the HCCA Scheduler. A Scheduler module implementing the reference scheduler defined in the draft IEEE 802.11e document is also described. The software framework re-ported in this paper has been implemented using the Net-work Simulator 2 platform. A preliminary performance analysis of the reference scheduler is also reported.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
