Replication Strategy in Manet to Increase the File Availability

The peer to peer file sharing in MANETs (Mobile Ad-Hoc Networks) gives the gravid impact in the world of communication and sharing. The file sharing in network like LANs, WLANs where server takes the brilliance and all tasks or file sharing activities done with processing queries on server. That gives lag querying processing and sometime due to rushing on server time out occurs. Importance is achieved due to communicability between peer groups or between un-peearable nodes. It is favorable for short and long terms goals because of sharing without central nodes. The time efficiency factor increases with query processing and p2p file sharing. The main importance is taken by file sharing in MANETs that is securely storing of files with File Replication in MANETs. In the literature there is some existed replication protocols in MANET that includes : File replication data allocated on mobile nodes in MANET and store it, Replicas are slenderize to neighbor nodes and then reduced or merged, The cache technique works, where query processing done in frequently encountered nodes and that nodes are used for file replication, The probability based system in which file replication done in that node who’s probability of adopting the replicas in the network is higher than other nodes in network. The PCS file replication protocol that works efficiently and minimizes querying processing delay in network. In our algorithm the replicas are created in fixed server where inside the server peers are available and file stored in encrypted format, so no unsafe can deal with proper file, so file is secured in MANET.
