Analysis of Mobility Management for Vertical Handover in Heterogeneous Wireless Networks

With the expanding domains of the wireless technologies the mobility offered by the system is usually expanding providing users to be able to move between various networks simultaneously. Since the mobility in heterogeneous wireless techniques, vertical handovers are very much more advanced than the conventional horizontal handovers used. Inside IEEE 802. 21 a new platform for a standard addressing a uniform and media independent framework is used for seamlessly handover between different technologies. It is known as Media Independent Handover (MIH). In past many years lot of research offers been completed for improving the handover between various access technologies. In this specific paper, we are proceeding to illustrate various handoff techniques implemented in typically the past. A comparative view proposes the efforts from the technique and their advantages and disadvantages.
