ABSTRACT
In order for non-mobile ORB to interoperate with CORBA objects and clients running on a mobile terminal, OMG have specified Wireless Access and Terminal Mobility of CORBA. In the common core of the CORBA specification, Fault Tolerance has been specified. But it is intended for the wired networks. This study proposes a fault tolerant architecture for the Telecom wireless CORBA based on replication and checkpoint of objects. The storage available at Access Bridge is employed to log messages and entity states of objects on behalf of mobile terminals. The logging and recovery infrastructures are designed on each Access Bridge, to implement the fault tolerant for Telecom wireless CORBA. The Logging Mechanism records the message in a log, from which the Recovery Mechanism can retrieve the message during recovery. The performance analysis shows that the proposed fault tolerant architecture ensures a low loss of computing incurred by the fault of the server object. The proposed fault tolerance architecture is a graceful extension of the original wired Fault Tolerant CORBA and is able to cooperate with the published CORBA specifications seamlessly.
