Multicast Service for Hierarchical Regional Registration Mobile IP Networks

摘要

In this paper, we consider the problem of providing multicast service for Hierarchical Regional Registration Mobile-IP (HRRMIP) networks. Using existing multicast protocols in a mobile environment is inefficient especially when dealing with frequent membership or location changes. This paper describes a new protocol for supporting IP multicast jor mobile nodes using IETF Mobile IP in the case of hierarchical networks. The basic unicast routing capability of HRRMIP is used to found a new efficient multicast service for mobile nodes. The proposed protocol is transparent to upper layers, simple and the simulation results show that it is robust, scalable and efficient.
