Abstract: Applications of file sharing in MANET have attracted more and more attention in last few years. The efficiency of file querying affected by the distinctive properties of such networks including limited communication range, node mobility and resource An efficient method to alleviate this problem is to create file replicas using the network. While considering the efforts on file replication, the research has not focused on the global optimal replica creation with minimum average querying delay. Preferably, current file replication protocols in mobile ad hoc networks have two shortcomings. In this paper, we introduce a new concept of file replication, which considers node storage and meeting frequency respectively. We theoretically study the flow of resource allocation on the average querying delay and we derive a resource allocation rule for minimizing the average querying delay. After that we propose a distributed file replication protocol for realization of the proposed rule. Extensive trace-driven experiments with real traces and synthesized traces to show that our protocol can achieve shorter average querying delay at a lower cost than existing replication protocols.
