In MANET data accessibility is reduced by the network partition. To minimize the degradation, most of them assume that all mobile nodes collaborate fully in terms of sharing their memory space. However, if there is only limited memory space and many of the nodes hold the same replica locally, then some data items would be replaced and missing. This will increase its own query delay. A node may act selfishly, i.e., using its limited resource only for its own benefit, since each node in a MANET has resource constraints, such as battery and storage limitations.
