Dynamic Hierarchical Location Management Scheme for Host Identity Protocol

摘要

In this paper, a dynamic hierarchical location management scheme for Host Identity Protocol called DH-HIP is proposed to support micro-mobility. DH-HIP has a three-layer architecture which is managed by Rendezvous Server (RVS), Gate RVS and Local RVS (LRVS) respectively. The host selects its LRVS and computes the optimal size of administrative domain according to its current mobility and packet arrival rate. Furthermore, an analytical model to study the performance of DH-HIP and HIP is presented. Analytical results show that the signaling cost is significantly reduced through DH-HIP compared with the IETF HIP scheme under various conditions.
