A Velocity-Aware Handover Trigger in Two-Tier Heterogeneous Networks
The unexpected change in user equipment (UE) velocity is recognized as the primary explanation for poor handover quality. In order to resolve this issue, while limiting ping-pong (PP) events we carefully and dynamically optimized handover parameters for each UE unit according to its velocity and the coverage area of the access point (AP). In order to recognize any variations in velocity, we app...
متن کاملDelaying Inter-tier Handover in Hierarchical Networks
In hierarchical network where a macro cell includes multiple small scale cells such as micro, femto cells and Wi-Fi hot-spots, preventing unnecessary handover is one of the most important matters due to so many inter-tier handovers. From the observation that there are many temporary visitors who stay in a small scale cell with short residence time, some recent handover schemes propose to delay ...
متن کاملCoordinated Two-Tier Heterogeneous Cellular Networks with Leakage Based Beamforming
In this paper we demonstrate the rate gains achieved by two-tier heterogeneous cellular networks (HetNets) with varying degrees of coordination between macrocell and microcell base stations (BSs). We show that without the presence of coordination, network densification does not provide any gain in the sum rate and rapidly decreases the mean per-user signalto-interference-plus-noise-ratio (SINR)...
متن کاملDownlink Interference Mitigation Scheme for Two-tier OFDMA Cellular Networks
In a two-tier cellular network, macrocells and femtocells coexist. Since femtocells use low transmission power and share network resources with macrocells, they are considered as one of the promising solutions to highly congested network environments. However, since femtocells are deployed in a selforganized manner without cell-planning, they cause severe downlink interference to macro users. T...
متن کاملA green handover protocol in two-tier OFDMA macrocell-femtocell networks
In this paper, we develop a green handover protocol in two-tier OFDMA macrocell-femtocell networks. To improve the energy efficiency of femtocell base station, the proposed green handover protocol can intelligently switch on its radio communication and associated processing, or called as “wake up” from the idle mode, if the remainder data of a mobile host can be completely uploaded through the ...
