A Comparative Study of Cluster-based Data Replication Techniques for MANETs
Data replication is one of the popular services in Mobile Ad-hoc NETworks (MANETs),and increase data availability by creating local or nearly located copies of frequently used items, reduce communication overhead, achieve fault-tolerance and load balancing. In MANETs, frequent network partitioning and the failure of mobile nodes due to exhaustion of their battery power and switch off mobiles can considerably decrease data availability. In this paper performance analysis of existing Cluster-based MANETs techniques based upon of available techniques into various classes, with respect to various issues they address (such as Client/server classification, Data availability and data consistency, Partition detection, etc.) is carried out.
