Providing seamless mobility among networks either heterogeneous or homogeneous has become one of the major challenging issues in next generation of wireless networks. Recently, within the past decade, researchers and IP-mobility communities have been investigating on performance of wireless networks in terms of providing seamless and smooth handover procedure while the Mobile Node detaches from current connected network and tries to connect to the most appropriate neighbor network. During performing handover procedure, Mobile Node may encounter connection problem which is a dramatically undesirable event especially for time sensitive applications such as VoIP and video conferences. Knowing the location of Mobile Node could save huge amount of time which results in significant reduction of handover latency. Thus this paper presents an overview on latest location-based handover schemes in both heterogeneous and Mobile IPv6 homogeneous networks.
