In a mobile ad hoc network, the mobile nodes will have the characteristics of mobility and constraints in resources. Since, the mobility is high, the nodes may move randomly and fastly, which lead to network partitioning. The resource constraints lead to a big problem as decrease in performance and the network partitioning leads to poor data accessibility. To improve the data accessibility, the authors have proposed several data replication techniques. Most of the users at different places assume that mobile nodes co-operate fully in terms of sharing their memory space. But In reality, some nodes may decide as not to co-operate with others or partially co-operate with other nodes. The behavior of these selfish nodes leads to decrease in over all data accessibility of the network.
