Analytical Modeling of a Traffic Differentiation Strategy for 802.11

Wireless communications are going to be the common way for individuals to connect with other people and to access Internet services. However, in spite of the many advantages exhibited by wireless technologies, they still have a number of drawbacks, such as poor reliability, limited throughput, scarce QoS and security support, limiting a wider applicability. An area that deserves attention is concerned with flexible mechanisms to guarantee and control the access to the communication medium under loaded conditions. Indeed, these mechanisms may represent the basis, for instance, to provide QoS guarantees to multimedia and other real-time applications, or to enforce protection from denial-of-service attacks.
