摘要：Mobile ad hoc network (MANET) is a selfconfiguring infrastructure less network of mobile devices connected by wireless. Ad hoc is Latin and means "for this purpose”. The nodes connected in the MANET network can move randomly in the connected network by replacing the different paths. Each Device connected in manet is responsible for routing the traffic as behaving like to that of a router. The main requirement in building a MANET is equipping each device to continuously maintain the information required to properly route the data packets. MANETs are a kind of Wireless ad hoc network that usually has a routable networking environment on top of a Link Layer ad hoc network. In mobile ad hoc networks (MANETs), nodes move freely and link/node failures are come devices in mon, due to that the data access will also be failure. In the case of network partition, the nodes from first network are not possible to access the data from the second network, due to that the performance becomes degrade of network. To solve this problem we used one new concept known as data replication, by the use of data replication the data availability will be increased. Node failure or link failure will not affect the data availability because when the data is accessing, at that particular instant of time the data is replicated to that node by which they are interacted, By that it improves the time of action.
