MacroFemto cell handover with enhanced QoS in Mobile WiMAX

WiMAX femtocell is developed to expand cell coverage, increase system capacity and offer various multimedia services with high throughput in indoor environments. However, several aspects of this new technology are ambiguous, such as macro to femtocell handover and management of QoS when a user moves between cells of different types. This paper provides a new procedure for handover between WiMAX macro and femtocells. Our proposal offers three key features: reduces the number of breaks in data submission, guarantees the QoS for the different connections of each user and finally provides load balancing between base stations and WiMAX Femtocell Access Point (WFAP). We validate our assumptions through simulations and numerical analysis. Results show the effectiveness of our solution.
