Abstract

Trends in high-performance computing are making it necessary for long-running applications to tolerate hardware faults. Checkpoints are used to store the specific states of processes in stable storage. When systems fail, they can recover to a consistency state from checkpoints rather than the beginning state. There are many checkpointing algorithms used in distributed systems. However, the checkpointing algorithms proposed for traditional distributed systems cannot be used in MANETs due to its unique characteristics such as low storage capacity, limited bandwidth, frequent disconnection, etc. Checkpointing technique can be basically classified into three categories that are: uncoordinated checkpointing, coordinated checkpointing and hybrid checkpointing. Uncoordinated protocols allow different nodes to save their local states independently of each other. In the coordinated protocols, a node coordinates the checkpointing. Hybrid checkpointing is the combination of two or more checkpointing algorithms. The aim of this paper is to analyze various checkpointing algorithms and its applications in MANETs.
