Abstract

The recent advancement in the field of wireless networking and mobile computing has led to the development of variety of applications for wireless networks. Mobile Ad Hoc Networks (MANETs) are emerging as one of the major wireless technology in the field of mobile computing. A MANET is a group of mobile devices or nodes that are self-configurable and can communicate using wireless links. The nodes of such a network have to be fault tolerableand processes must execute without any failure. Checkpointing is one of the recovery techniques that can be used to make mobile device fault tolerant by taking a snapshot or an instance of current state of application or process and storing it at stable memory space and in case of failure uses it to resume the computation from current checkpoint in-spite of resuming it from the beginning and thereby reduce the time for recovery. In this paper the performance analysis of two existing asynchronous checkpointing algorithms in cluster basedMANETs has been presented on the basis of parameters number of failures, number of recovery messages needed, number of clusters and recovery time.Cite this ArticleSushant Patial, Jawahar Thakur.
