Mobility Support in HIP Based on Dynamic Hierarchical Location Management
基于动态层次位置管理的HIP移动性支持机制

The existing mobility support scheme in Host Identity Protocol (HIP) does not support micro-mobility. In this paper, a new mobility support scheme in HIP based on dynamic hierarchical location management is proposed. The Internet is separated into some autonomous areas while each autonomous area is separated into some registration areas. When the node moves in the same registration area, it updates its registration at Local RendezVous Server (LRVS). When the node moves in the same autonomous area, it updates its registration at Gateway RendezVous Server (GRVS). The node selects LRVS and determines the optimal size of registration area according to its mobility and packet arrival rate. Analytical results show that the new scheme outperforms the existed mobility support scheme in terms of reducing the overall signaling cost.
