Abstract—We propose a velocity-based bicasting handover
scheme to efficiently utilize backhaul network resources in
Fourth-generation (4G) mobile systems. The conventional bicasting
scheme makes all potential target base stations hold
the user data, thus it can achieve seamless connectivity by
minimizing the packet fluctuation delay caused by handover.
This scheme, however, leads to an aggressive consumption of
resources at the backhaul network. When this scheme is widely
adopted for real-time services and the demand for these services
increase, the amount of backhaul network resources consumed
due to bicasting will also increase tremendously. Therefore,
we proposed a velocity-based bicasting scheme which reduces
the bicasting time and thus, improves the backhaul network
resource utilization. Our scheme uses a novel concept of bicasting
threshold determined on the basis of specific mobile speed groups.
The simulation results prove the efficiency of our scheme in
overcoming the aggressive resource consumption at the backhaul
network
