Transient-Snapshot based Minimum-process Synchronized Check pointing Etiquette for Mobile Distributed Systems

Minimum-process harmonized checkpointing is well thought-out an attractive methodology to acquaint with fault tolerance in mobile systems patently. We design a minimum- process synchronous checkpointing algorithm for mobile distributed system. We try to minimize the intrusion of processes during checkpointing. We collect the transitive dependencies in the beginning, and therefore, the obstructive time of processes is bare minimum. During obstructive period, processes can do their normal computations, send messages and can process selective messages. In case of failure during checkpointing, all applicable processes are necessitated to abandon their transient snapshots only. In this way, we try to reduce the loss of checkpointing effort when any process fails to take its checkpoint in coordination with others. We also try to minimize the harmonization message complexity during checkpointing.
