Abstract:
WiMAX femtocells are currently under the development and they are expected to play an important role in the development of indoor broadband wireless access. Multiple femtocells are overlapped in WiMAX network for the purpose of improving coverage. The signal strength of WiMAX base station is usually stronger than the femtocell, hence there is no chance of handover. This paper thus proposes the velocity decision handover mechanism is used to reduce neighbor cell list for successful handover. The simulation results show that our scheme improves femtocell usage, offload the traffic of macrocell and decrease the handover delay compared to the conventional mechanism.
