摘要：Increasing data or service availability is a major concern of any network / computing environment. A user in a network may encounter the problem of data unavailability due to several reasons such as server crash, network partition, link failure etc. Data is replicated in several systems in order to make it available to the user in presence of any network problems as stated above. A network can be characterized based on the type of systems, communication medium and the mobility of systems. There are several types of network/ computing paradigm that has evolved which are diverse in characteristics and functionality. Though replication has been known as a popular mechanism to increase data availability in traditional networks, a need for contemporary solution arises along with evolution of recent Network/computing paradigms such as Mobile Ad –Hoc, Vehicular, Cloud and IoT. As these environments are characterized diversely, each of them demands a customized replication approach. We perform an indepth survey on various replication approaches used in different computing environment with varying network entities. We present the possible scope for future research in Replication for various computing paradigm.
