| Summary: | Femtocell is a small base station that deployed in homes, buildings or other locations and designed to improve indoor capacity and signal coverage, and also reduce the macrocell traffic Femtocell becomes a solution for indoor capacity and coverage issues. Frequent and unnecessary Handover is another issue in femtocell network. The UEs with various velocities moving through the femtocell usually lead problem and perform frequent and unnecessary handovers especially for high speed users. These cause the reduction of the system capacity and the QoS level. In this project, handover algorithm between macrocell and femtocell has been proposed and developed based on User Equipment (UK) velocity and Receive Signal Strength (RSS). The proposed handover algorithm divide into two parts which is handover from macrocell to femtocell (hand-in) handover from femtocell to macrocell (hand-out). This proposed algorithm was developed and simulated to evaluate the performance of handover procedure in order to minimize an unnecessary handover, enhance the system capacity and improve the user's QoS level in the femtocell networks. Simulation results show the proposed algorithm gives the better simulation result and achievement to minimize an unnecessary handover and also decrease the number of handover failure. The handover procedures between macrocell and femtocell by using proposed scheme are efficient and reliable compared to conventional handover. The optimization of handover procedure and algorithm will improve the performance of both femtocell and LTE networks. |
