| Abstract | In this thesis we study user impatience and quantify its impact on the performance of mobile networks in the presence of elastic user in which we develop two approximate expressions for the stationary distribution of the system: an aggregate one and a detailed one and show their closeness to the exact model. We study mobility of elastic user who may be impatient and quantify its impact on system performance in mobile networks. We consider the case of mobility due to impatience during the prefetching and the re-buffering phases when starvation happens. We finally study a system with impatient users controlled by a system manager who has to choose at each decision epoch an action to make in order to optimize the defined system performance. We consider a system in which users come to the system at different time instants and leave it after a finite duration, either after completion of their data transfers or earlier, at the expiry of some patience duration. Numerical analysis and simulations allow us to derive several performance metrics such as mean number of users, the proportion of impatient users who quit the system before completing their file transfers, the throughput, the probability of starvation, the optimal system size in order to optimize the defined performance of the system, etc... |
