Abstract

Hierarchical Mobile IPv6 (HMIPv6) reduces the amount of signaling overhead between the Mobile Node (MN) and its Correspondent Node (CN) by introducing a mobility anchor point (MAP). However, handling both intra-domain handovers and tunneling traffic for MNs may cause a single point overload. In this paper, we present a MAP (Mobile Anchor Point) selection scheme based on Multi-attribute Decision Making (MADM). In our proposed scheme, the Pref and Dist in MAP option message are used as two attributes of MAP, and MN can set different weights for these two attributes according its velocity. After testing, it indicates this scheme can handle high level MAP overload and achieve better communication performance.
