Fast-Handover Mechanism between 802.11 WLAN and 802.16 WiMax with MIH in PMIPv6

As the wireless Internet services become widely available, users become able to use various Internet services without restriction in location. In particular, the demands on wireless Internet services are becoming greater, because mobile devices that support high mobility are getting smarter. However, if a user uses various wireless networks, much limitation occurs in network setting when they move a network different each other. This is because there are few appropriate handover mechanisms to support a heterogeneous network. We propose a fast-handover for heterogeneous networks that utilizes MIH in PMIPv6 to support heterogeneous networks and to reduce the handover latency time. The result presented shows that suggestion has reduced latency time of 26% and packet losses of 90% (Avg.).
