A mobile computing system is a distributed system in which at least one of the process is mobile. They are constrained by lack of stable storage, low network bandwidth, mobility, frequent disconnection and limited battery life. Checkpointing is one of the commonly used technique to provide fault tolerance in mobile computing environment,. In order to suit the mobile environment an optimized approach to checkpointing is proposed that will mainly focus on the limitation of the mobile computing system and thus saves cost by reducing the overhead of transferring large amount of data to the stable storage at the mobile support station.
