A novel architecture for hierarchically nested network mobility

Abstract

We propose an efficient location management scheme based on collaboration of mobile nodes in a mobile network. This proposed scheme integrates Hierarchical Mobile IPv6 with Network Mobility to manage macro mobility and seamless handoff. We address the key functions of the proposed scheme and analyze the performance of our proposed scheme mathematically. We show that our proposed scheme perform much better than Network Mobility, especially when the number of mobile nodes, mobile routers, or correspondent nodes increases in hierarchically nested mobile networks.
