Résumé en anglais

The fourth generation has been based on the development of the Internet in the air interface. The current Internet lacks the quality of service support. A previous contribution proposed the development of a new protocol (MIR: mobile IP reservation protocol), which provides quality of service guarantees to a mobile terminal [J. Benothman et al., 2000]. To show the benefit of this protocol we propose in this study to make performance evaluation of this protocol. Performance evaluation of this kind of network is difficult because we take into account a lot of parameters such as the cell number, buffer size for data, connection voice number in a cell, handover, etc. Thus the mathematical model associated to this network cannot be solved by a numerical method because of the size of the Markov chain, which is too large. In this study, we propose to use stochastic automata networks to make our performance evaluation.
