Femtocell technology has drawn considerable attention as a cost-effective mean to improve cellular coverage and capacity. Data loading and offloading to the macro Base Station (mBS) is supported through internet backhaul which exhibits the uniqueness of this technology. Interference is one of the most challenging phenomenon's that arise due to the non-synchronized femtocell. It is known that fBS and macrocells Base Station (mBS) network operates on the same frequency under a licensed spectrum hence; fBS network can interfere with the macrocells network. However, in this paper, cluster-based synchronization scheme has been proposed which functions through clustering, inter-cluster synchronization scheme. The proposed scheme mainly focuses on reducing the clock offset and skew as well as message overhead. Cluster-based synchronization scheme provides high scalability and works in a decentralized manner which can support a large number of fBS networks with a satisfactory performance level in term of synchronization accuracy. In this paper, it has shown that proposed scheme's synchronization accuracy is higher than any of the existing schemes so far. [ABSTRACT FROM PUBLISHER]

With the intention of establishing the connectivity between the femtocell and the core network, it is essential to use public network that ultimately creates several challenges for the operators. Therefore, Synchronization is considered corner stone and has become one of the most significant issues in femtocellular networks to ensure a tolerable carrier offset as well as support received signals in order to reduce multi-access interference. In this paper, one potential synchronization schemes for femtocell are presented which is intra-cluster synchronization scheme. An intra-cluster synchronization scheme is proposed to minimize the clock offset for the better synchronization accuracy. The analytical result shows that the proposed scheme can achieve synchronization accuracy up to 90% higher than the existing MS-assisted schemes. [ABSTRACT FROM PUBLISHER]
