IEEE 802.11e is the draft of amendments introducing QoS (Quality of Service) to the IEEE 802.11 standard. 802.11e supports HCF (Hybrid Control Access) combining two Access modes: EDCA (Enhanced Distributed Channel Access) and HCCA (HCF Controlled Channel Access). EDCA is a distributed channel access function enabling prioritization. In this paper we will discuss problems inherent to collision management within EDCA.
