STUDY ON RESOURCE MANAGEMENT SYSTEM FOR INTERFERENCE MITIGATION IN FEMTOCELL NETWORKS

Cellular phones play an important part in modern day life. At present it's very uncommon to see a person without using mobile phones. Due to Increasing mobile users across globe, rising trend of multifloor and intricate designed apartments in inner-city area, poor coverage found as a key issue. To surmount this femtocell allows service providers to extend service coverage inside of home - especially where access would otherwise be limited or unavailable. It also decreases backhaul costs since it routes cellular phone traffic through the IP network. A femtocell is a miniature cellular primary station intended for use in inhabited or small industry environments. A femtocell is sometimes referred to as a residential base station, way in point base station, 3G way in point, miniature cellular primary station and private 2G-3G base station. WIMAX STD IEEE 802.16 and Long Term Evolution (LTE) femtocells provide a variety of high data rate service to the end users. LTE femtocell is being considered as the future equipment at the indoor environment[2]. Interfering alleviation between neighbouring femtocells and between the femtocell and macrocell is taken as one of the major challenges in femtocell networks because femtocells allocate the same accredited frequency spectrum with macrocell. This report provides a analysis on the different state-of-the-art methodology for noiseless and resource management in Orthogonal Frequency-Division Multiple Access (OFDMA) based femtocell networks and offers an optimal solution[13]. One of the most crucial issues is the design of a very capable scheduling algorithm which synchronizes all other QoS-related well-designed entity.
