Abstract
To support efficiently the high-speed service and the multimedia service in mobile communication environments, network architecture is generally based on small cell radius structure to increase the wireless channel capacity. In a small cell radius structure based mobile network environment, a mobile station with large mobility should perform frequent handover. Thus, an advanced handover mechanism should be provided, and must be done quickly. For these reasons, we suggest an efficient handover mechanism based on the forward handover method in this paper. The proposed handover mechanism could support a fast handover procedure, and is performed by using an optimized path. Also, the proposed handover mechanism could support QoS (quality of service) attribute of multimedia traffic during the handover procedure. We evaluated the performance of the proposed handover mechanism, and analysis results show that the suggested forward handover mechanism has less blocking ratio and lower delay than the conventional backward handover mechanism.
