The femtocell concept is an emerging technology for deploying the next generation of the wireless networks, aiming at indoor coverage enhancement, increasing capacity, and offloading the overlay macrocell traffic. Nevertheless, one of the most critical issues in femtocells deployment is the potential interference, thus mitigating the overall system capacity. Inspired by the cognitive radio technology which enables a station to cognize and adapt to the communication environment to reach the optimum network performance, this paper presents a joint power control and scheduling algorithm for interference management in femtocell networks. Simulations were conducted under Matlab. Theyshow the efficiency of our proposal and its ability to improve the overall throughputas well asreducing the energy consumption.
