Abstract:

Wireless network users are increasing vastly in present days and the data traffic in mobile communications systems is increasing explosively too. To cover maximum user with limited radio resources and to provide high quality of service (QoS) to the user, a fractional frequency reuse (FFR) techniques have been proposed for hybrid cellular wireless network. A femtocell can provide high-quality services to indoor users with less power consumption while a macro cell can serve the mobile user of a network. However, the FFR can cause huge interferences to the mobile station and the base station of same frequency. In this paper, we proposed an efficient dynamic FFR scheme that ensures high-quality of service with interference reduction. We propose that if channels are borrowed from adjacent cells, femtocell bifurcation will be introduced that ensures interference reduction when the borrowed channels have same frequency band. We also propose a scheme that inactivates the interfering channels of adjacent cells. The simulation outcomes show acceptable performances in terms of signal to interference ratio (SIR) level, system capacity, and outage probability compared to conventional scheme which does not include any interference reduction technique.
