Abstract

In this paper, we propose a new interference management scheme for femtocells systems based on the cooperation and inter-handover techniques between competing cells in the context of cognitive radio systems. The original idea presented in this work consists of initiating a cooperation protocol between femtocells through inter-handover algorithm based on channel gain diversity. Users belong a given femtocell are allowed to connect to a neighboring cell if their channel gains to this cell are better than what they have with their own femtocell. We have shown in this work, using a game theory based resource allocation scheme, that we can achieve better performance in terms of capacity and power consumption using our approach. The results have shown also that a simple win-win cooperation protocols can be implemented to improve the energy consumption and performance of new cellular systems such as femtocells or even for classical cellular systems if a minimum cooperation schemes are allowed.
