Priority-based Transmission in IEEE 802.11 Networks
Tomasz Janczak, Józef Woźniak · Kluwer Academic Publishers eBooks · 2005
Nowadays, Internet faces growing demand for carrying on multimedia traffic. Therefore, many standardization bodies work on solutions, which introduce service differentiation and QoS guarantees for Internet protocols. However, all new modifications made in the network (IP) layer would be of little value without complementary solutions implemented in lower layers. Applying of service differentiation mechanisms into the MAC (Medium Access Control) level is a challenging task, especially for wireless Local Area Networks (WLANs), due to their dynamic nature. In this paper, we propose a QoS support scheme for the IEEE 802.11 standard, based on strict frame priorities.
