Improvement of Coexistence of LTE Femtocell Network with Dynamic Resource Allocation

In the current scenario, interference is one of the most challenging problems we are facing in femtocell deployment under the coverage of existing macrocell. Allocation of resources between femtocell and macrocell is essential to counter the effects of interference in dense femtocell networks. Advances in resource management strategies have improved the control mechanism for interference reduction at lower node density, but most of them are ineffective at higher node density. In our research work, a dynamic resource allocation management algorithm for spectrum shared hybrid access is accomplished in a femtocell network. In base paper only throughput is represented with FAP but in our research work we set up cognitive radio network (CRN), comparison between power used by Femto cell and macro user and power factor is very important parameters in our daily life and when there is comparison between Femto and macro Femto cell user consume very less power as compared to macro. Besides this, in our research work, we show the throughput and power used by Femto cell at different floor and result clearly shows that if Femto cell used on the same floor then coverage area will be more with respect to that if used at different floor. Power consumption between macro and Femto user shows us that Femto user utilizes very less power as compared to the macro user.
