Comparison of Mobility Management Protocols in IP Networks

Abstract

With recent advances in wireless communications technology, mobile computing and networking becomes an increasingly important research area. Enabling mobility in IP networks is a significant issue for making use of many portable devices appearing on the Internet. Several protocols and proposals, such as Mobile IP, Cellular IP, HAWAII, Hierarchical Mobile IP, SIP, etc, have been developed to support mobility. These mobility protocols will play an important role in the convergence of IP networks and telecommunication networks. In this paper, we address two important components of mobility management: location management and handoff management. Mainly, this paper reports a comprehensive comparison of each method qualitatively from various technical viewpoints.
