Abstract :
The home agent can be a single point of failure in mobile IPv6 networks. Fault tolerance can be used to provide reliable home agent service. This paper proposes a home agent fault-tolerant method for mobile IPv6 networks. All home agents are formed into the structure of ring detection & backup chain by sorting them using a deterministic sorting algorithm, in which each home agent backups its bindings on the next adjacent home agent and its validation is monitored by the adjacent home agents. Each home agent is not only an active home agent, but also a standby one. Service takeover is fleetly implemented by the single replica of mobility bindings. Simulation results show that our method has less service break time and less global signal cost.
