The effect of femtocells and the mobile users on the throughput of the LTE-A network using an open source simulator

Recently, femtocells are likely to be deployed at homes and small enterprises in an urban area to improve the coverage and capacity of the systems. Thus, in order to improve QoS in wireless and mobile networks overlay an existing macrocell network with indoor femtocell is an alternative solution for service operators. Mobility is also one of the main issues in performance evaluation of wireless systems. There is a lack of analysis that provides the deployment of femtocells in an existing macrocell network considering the mobile users. Hence, the impact of mobile users and the deployment of femtocells in a macrocell presented using an open source simulator. An open source simulator is adapted and different scenarios are considered for a typical urban area as case study where a set of femtocells are deployed within the coverage area of a macrocell. The numerical results presented show that the deployment of the femtocells improve the overall QoS considering the mobile users.
