Introduction of Femtocells in heterogeneous network enhances the capacity, indoor coverage of the existing macrocell based network. It also allows high-speed data services for the multi-media application and software. However, in dense co-channel deployment scenarios femtocells cause severe interference to the neighbouring cells users. In this paper, a downlink-power-control scheme is presented for...
The increase in popularity and pervasiveness of mobile wireless networks is facing the challenge of integrating a potentially large number of heterogeneous wireless technologies to provide efficient handover schemes and flawless mobility. Fast handover proximity entity (HOPE) is a scheme introduced to support fast and efficient handovers in heterogeneous cellular networks. The proposed method demonstrate...
Substantial capacity gains and enhanced cellular coverage can be achieved by hierarchical deployment of femtocells over existing macrocell networks. However in co-channel deployment scenarios, femtocells can cause severe interference to the neighbouring cells and drive users into outage. Properly selecting femtocell base station transmit power level helps managing the interference, while maintaining...
