摘要：To several mobility management protocols proposed for IP-based mobile networks, fault tolerance aspect of mobility agents is a primary requirement to sustain continuous service availability to the mobile hosts. For a localized or micro- mobility management solution, the local mobility agent i.e. gateway is a single point of failure because it is responsible for enforcing the signaling and data packets in its domain. Such failures may severely disrupt the communications among the failure-affected users. The problem becomes even more severe for mobility agents in a distributed mobility management scheme with overlapping registration areas. This paper proposes a fault tolerance scheme for Distributed and Fixed Hierarchical Mobile IP (DFHMIP) and evaluates its performance in terms of data transmission cost and blocking probability.
