CORE BASED TREE MULTICAST (M-CBT) APPROACH IN SUPPORTING MOBILITY

摘要

IP multicasting provides a mechanism for faster handoff support than Mobile IP. Coupled with its location independent addressing, multicasting is a viable alternative to support mobility in the Internet. This paper continues research into using IP multicasting in mobility. Our proposed scheme looks at enabling a mobile node to initiate two. way communications with a corresponding node on a shared multicast tree. We use as much of the existing Internet architecture as possible by making the base-station a member of the multicast group. The mobile is not directly connected to the tree but goes through the base-station to send and receive packets. This paper explains the differences and advantages of our proposed scheme compared with other multicast based mobility schemes and Mobile IP.
