Cluster-based multihop synchronization scheme for femtocell network

Femtocell technology has been drawing considerable attention as a costeffective means of improving cellular coverage and capacity. It is connected to the core network through an IP backhaul and can only use timing protocols such as IEEE1588 or Network Time Protocol (NTP). Furthermore, the femtoce...
