This paper gives an overview about the QoS and mobility mechanisms in several network environments: Wireless Local Area Network (WLAN) radio access, Evolved Packet Core (EPC), and 802.16 WiMAX radio access. A number of solutions aiming to provide QoS at the network layer are also covered, together with a comparative analysis of the mobility mechanisms within each technology, analysis that highlights the similarities and differences between these environments, as well as their drawbacks. The paper shows, that further research is required in the end-to-end QoS and mobility area, both in the wireless access networks as well as the core network.
