%X This paper introduces RSVP, MRSVP and the QoS guarantee mechanism in mobile IP by utilizing the MRSVP. Three HMRSVP schemes are described and compared in detail, especially the HMRSVP with pointer forwarding. A modified one is proposed. In this scheme, MH in a hierarchical region uses pointer forwarding scheme, which can utilize the feature of movement locality. When it moves into a new region, it is required to update the RSVP path and begin the new pointer forwarding process. Also, the feature of locality is discussed thoroughly. The modified scheme is modeled and analyzed in two different cases. The results show that it has better performance.
