Femtocells QoS management with user priority in mobile WiMAX

Femtocells are an inexpensive solution to address weak indoor cellular coverage. Femtocells increase network coverage, offloaded macro cell sites, and provide high data rate services in a cost-effective manner. However, several aspects of this new technology are ambiguous or not defined in standard, such as QoS architecture, bandwidth request management and subscribers flows priority. This paper provides a new QoS management scheme for WiMAX Femtocell Access Point (WFAP). Our proposal offers three key features: prioritize femtocell's owner traffics; guarantee's the QoS for the different connections of each user, better resources management. We validate our assumptions through simulations and numerical analysis. Results show the effectiveness of our solution in public and private access methods.
