Utility based function for optimizing femtocells

The need for network coverage in an indoor setting has brought the acceptance of femtocell as a solution. The remarkable of these new technology called femtocell improves coverage, enhances the data rate more than the macro cell. The mobile operators must always ensure an optimal network that results to quality performance of service. Thus quality of service indicates the most significant for the satisfaction of networks user, particularly for the deployment of the femtocell. Here, we focus on the deployment of femtocell through the utility function to optimise each region of deployment of the femtocell in the cellular network. The utility-based function takes into account the transmitting power of each region and the capacity of the system. This reduces interference constraint within the regions and optimises the network. Through the simulation results, we show that utility based function enhances the optimal system within the regions of the cellular network.
