Wireless and mobile networks have many advantages as easy deployment, user mobility and provide network access to users regardless of their locations. The most critical problems that arise in these networks are on the resource allocations as the bandwidth is limited, the propagation (multi-path, fading, distortion) and security since communications are transmitted over radio waves. 

In this lecture, I will present several works done to model/Improve Quality of Service in Wireless networks.  Three different methods will be presented in this lecture.  In the first part, a new model based on Markov chains is presented to model the different service classes defined in IEEE 802.16. The second part I will present a new AC that we have defined for IEEE 802.16 and we have evaluated using Stochastic Automata Networks. Finally, I will present a stochastic comparison for admission control in wireless networks using IEEE 802.11 standard.
