This work proposes EcoRep a novel economic model for dynamic replica allocation in M-P2P networks. EcoRep ensures fair replica allocation while discouraging free-riding. EcoRep deploys a replica allocation algorithm which considers relative importance of data items load and energy issues user mobility patterns replica consistency and number of neighbours of a given user. Our performance study demonstrates that EcoRep is indeed effective in improving query response times and data availability in M-P2P networks., In mobile ad-hoc peer-to-peer (M-P2P) networks, frequent network partitioning leads to typically low data availability, thereby necessitating data replication.
