Mobile agent fault-tolerant method based on ring detection & backup chain
Hanwen Zhang · Journal of Communications · 2011
The home agent(HA) fault-tolerant method was proposed based on ring detection backup chain(DBCM) for mobile IPv6(MIPv6) networks.All HA in the same link were formed into the relationship of validation detection and information backup based on the deterministic ordering method.The latency of failure detection was reduced by validation detection among HA.Service transfer was fleetly implemented by the replica of registration information between neighboring home agents.The results of theoretical analysis and simulation show that our method has less service break time.Simulation results also show that our method has less application packets dropping ratio and global signal cost in the scenario that multiple home agents break down continuously.
