Abstract: “Femtocell is a small base station designed to increase the wireless network capacity and extend the coverage. It is a promising solution to overcome the tremendous growth in mobile traffic and indoor coverage problem. In this paper, extensive simulations have been carried out to evaluate the performance of the femtocell in an urban scenario, which compromised of indoor and outdoor users. The simulations are modelled in a heterogeneous network which consists of macrocell and femtocells. Femtocells are selectively deployed in an indoor environment. Proportional Fairness (PF), Modified Largest Weight Delay First (MLWDF) and Exponential Rule (ER) are used as the downlink scheduling algorithms. Simulation results show that femtocells significantly improved the network total throughput (~1200%) compared to the macrocell only scenario. Packet delay and packet loss ratio of video flows are reduced by 70%. Meanwhile, fairness index of video flows are also improved by up to 50%.”
