Abstract
The rapid increase in quality performance and the high data rate in the next generation of a cellular mobile network make the small cell an attractive solution to get a high data rate and low signal delay. The small cell can boost services to
many users at a low price, and it can guarantee a high data rate and capacity
within the indoor residential. There are three main types of small cells, including femtocells, picocells, and microcells.The macrocell is a base station with high power that can cover up to 200 miles of cell radius. However, it also suffers from various issues such as interference. The propagative of the femtocell over the macrocell can cause interference between the femtocell and the macrocell as they use the same spectrum. Also when the user moves across a macrocell overlaid with femtocells,the ongoing
call or data session is transferred from one base station to other while
maintaining the services. This process is called Handover.In our thesis, first, we study the performance of fixed power control algorithm
for femto/macro-user to increase throughput and signal-to-interference plus noise ratio ( SINR). Also, we combine different types of power control with frequency allocation (FA) algorithms to reduce the interference. Finally, we propose an algorithm that combines the fixed power control, fractional frequency reuse (FFR),
and resource scheduling algorithm and applying the handover technique. Our
proposed algorithm improved SINR, throughput, and mitigated the interference and the dropped calls, then the average throughput, the cell total throughput, and spectral efficiency are improved. Also the packet loss ratio (PLR) and the numberof handovers are reduced for different velocities.
