Abstract

As the number of portable devices roaming across the Internet increases, the problem of routing packets to mobile hosts generates increasing research and commercial interest. To support mobility more effectively for seamless provision of various applications, many multicast-based localized mobility support schemes have been proposed to achieve better performance than the basic solutions provided by the IETF, such as Mobile IP and Mobile IPv6. However, any multicast-based scheme inherently introduces significant bandwidth wastage at the wireless access network due to long leave latency. In this paper, we propose a new multicast group managment scheme that is tailored for managing multicast groups used to support host mobility. It has been shown by simulation that the proposed scheme achieves extremely short leave latency and eliminates bandwidth wastage in the wireless links.
