Vol. 6  No. 5  pp. 95-104


In this paper, we present a single phase non-blocking coordinated checkpointing algorithm suitable for mobile computing environments. The distinct advantages that make the proposed algorithm suitable for distributed mobile computing systems are the following. It produces a consistent set of checkpoints, without the overhead of taking temporary checkpoints; the algorithm makes sure that only minimum number of processes are required to take checkpoints in any execution of the checkpointing algorithm; it uses very few control messages and the participating processes are interrupted less number of times. Performance analysis shows that our proposed approach outperforms some existing important related works.
