A Review of Approaches for Compassionate Checkpointing with Mobile Computing Systems

A distribution system is a group of autonomous entities working together to address a challenge that cannot be addressed by any one of them alone. A distributed system called a mobile computing device (MCD) has certain processes that are executed on mobile nodes, whose position within the network shifts over time. Distributed mobile systems create new problems such as mobility, poor wireless channel bandwidth, disconnections, low battery life, and a lack of a steady, trustworthy store on mobile nodes. The issue of fault-tolerant computation in mobile distributed databases is discussed in this study. Checkpointing and roll-it-back recovery are the foundations for the procedures outlined.
