Mobile computing introduces new flexibility such as continuous access to computing resources while the users travel.This facility raises new challenges such as fault tolerance in distributed mobile computing system. In this paper we present a non blocking token ring based checkpointing algorithm to tolerate the faults in the mobile computing environment. It is a single phase algorithm neither having the overhead of temporary checkpoints nor using dependency vector; and also it avoids the avalanche effect. Results shows that it outperforms two-phase algorithms.

Abstract


Mobile computing introduces new flexibility such as continuous access to computing resources while the users travel.This facility raises new challenges such as fault tolerance in distributed mobile computing system. In this paper we present a non blocking token ring based checkpointing algorithm to tolerate the faults in the mobile computing environment. It is a single phase algorithm neither having the overhead of temporary checkpoints nor using dependency vector; and also it avoids the avalanche effect. Results shows that it outperforms two-phase algorithms.
