Now-a-days, the authors have effectively use wireless devices like mobiles which are one of the wireless ad hoc devices. In MANET, many times they want access of the data from other mobile. Since mobile nodes do not have fixed location or link and in such condition, if a node or link fails then there may occur frequent network partition, where mobile nodes in one partition cannot access data held by nodes in other partitions. Also data availability in MANETs is lower than that in conventional wired networks. Data availability i.e. the number of successful data accesses over the total number of data accesses is less and hence degrades the performance of data access.
