OFDMA femtocells are generally accepted as a very promising solution for indoor coverage with high data rate. However, the lack of systematic schemes to effectively mitigate macro/femtocell hierarchical interference, fully utilize radio resources, provide quality-of-service (QoS) and fairness guarantee among users suffocate the performance realization of femtocells. In this paper, an Adapted Soft...
Recently, femtocell has been proposed as a good solution to increase the coverage area and capacity of the wireless communication system as well as meet the increasing demand for high data rate. The femtocell is low-cost, low-power and can be realized by deploying a femto-base-station connected to the core network via a wired-backhaul. Since the femtocell reuses the macrocell spectrum, co-channel...
In a B3G/4G wireless communication system, the users will connect to the network using one of several available radio access technologies. In this paper, we proposed a Q-learning based algorithm for terminals' independent access network selection with the aim of improving the resource utilization and providing the best quality of service with respect to the wireless environment status, network performance...
The coexistence of different heterogeneous Radio Access Technologies (RATs) is a significant feature of current wireless networks. Thus, it is important for network elements, such as the Base Stations (BSs) of cellular networks or access points (APs) of wireless local area networks (WLANs) to be reconfigurable according to the real-time network environment. This will enable interconnection between...
