The emerging mobile wireless environment posses exciting challenges for distributed fault tolerant (FT) computing. Thi paper propose a message logging and recovery protocol on the top of Telecom Wireles CORBA and FT-CORBA architectures. It uses the storage available at the access bridge as the table storage to log messages and checkpoints on behalf of a mobile host. Our approach engages both quasi-ender-based and receiver-based logging methods and makes seamless handoff in the presence of failures. The details of how to tolerate mobile host disconnection, mobile host crash and access bridge crash are described. The normalized execution time of a mobile host engaging our proposed scheme and the handoff effect are evaluated.
