Abstract
This paper presents the performance evaluation of the checkpointing and rollback-recovery protocols for distributed mobile
systems, guarantying client-centric consistency models, despite failures of servers. The performance of considered protocols
is evaluated by estimating the checkpointing overhead. Additionally, the paper disscusses the influence of the consistency
models provided by the system on the moments of taking checkpoints. The impact of the obtained results on strategies for checkpointing
in the mobile environment guarantying client-centric consistency models is assessed.
Keywords checkpointing - rollback-recovery - performance evaluation - distributed mobile systems - session guarantees
