An improved architecture for minimizing handover latency in MIPv6

With the advent of mobile devices, the internet now undertook a huge and unexpected explosion of growth. The wireless mobile internet gives users access to the internet services while they are on the move. This mobility has been supported through the Internet Protocol known as Mobile IP. Mobile IP allows users with mobile devices to have continuous network connectivity to the internet without changing their IP addresses when moving from one network to another. While on move, the Mobile Node (MN) undergoes a handover process, in which the MN gets disconnected from one network and tries to connect to another network, i.e., New Access Router (NAR). The handover process involves various time-consuming procedures as Neighbor Discovery, Care-of-Address (CoA) configuration, Duplicate-Address-Detection (DAD), Binding Registration and Route Optimization. Various researches have been devoted to the acceleration of movement detection and registration. However, a time-consuming operation, i.e., duplicate-address detection (DAD), was overlooked by most studies. An improved architecture for minimizing the handover latency in MIPv6 is improved in this paper. The improved architecture suggests the removal of DAD procedure and configuration of a new CoA for the MN by the NAR. The result is evaluated on the basis of numerical analysis.
