As the wireless Internet services become widely\r\navailable, users become able to use various Internet services\r\nwithout restriction in location. In particular, the demands on\r\nwireless Internet services are becoming greater, because mobile\r\ndevices that support high mobility are getting smarter.\r\nHowever, if a user uses various wireless networks, much\r\nlimitation occurs in network setting when they move a network\r\ndifferent each other. This is because there are few appropriate\r\nhandover mechanisms to support a heterogeneous\r\nnetwork.We propose a fast-handover for heterogeneous networks\r\nthat utilizes MIH in PMIPv6 to support heterogeneous\r\nnetworks and to reduce the handover latency time.\r\nAnd the performance evaluation for the proposed method\r\nwas done separately for low speed and high speed mobility.\r\nThe result presented shows that the suggested method has\r\nreduced latency time by 26 % and packet losses by 90 %\r\n(Avg.).
