IEEE 802.11e Hybrid Coordination Function (HCF) Simulation Module for ns-2

The official distribution of the public domain network simulator, ns-2, only supports Distributed Coordination Function (DCF) in the IEEE 802.11 Medium Access Control (MAC) layer [1]. We constructed a functioning IEEE 802.11e HCF MAC simulation module for ns-2.28. The model is developed on top of the TKN ns-2.26 EDCF patch [2]. The model includes all the Enhanced Distributed Channel Access (EDCA) and HCF Controlled Channel Access (HCCA) functionalities stated in [3]. All HCF Quality-of-Service (QoS) data/control frame exchange sequences as well as optional Dynamic Link Setup (DLS) and immediate Block ACK implementations are supported. The module implements abstract PHY layer models for IEEE 802.11a/b/g/n. Moreover, AWGN channel support is included.
