In today's environmental world, no organization has time to wait for hours to receive data through various network channels. Everyone is looking forward to develop the Quality of Service (QoS) parameters during data transfer. IEEE 802.11e standard for QoS in Wireless Local Area Networks (WLANs) can activate with the Differentiated Service (DiffServ). IEEE 802.11e has established a new access mechanism called the Hybrid Coordination Function (HCF) that combines a contention-based Enhanced Distributed Channel Access (EDCA) and a contention free HCF Controlled Channel Access (HCCA) in a single function.
