Disruption Tolerant Networks (DTNs) is characterized by low node density and unpredictable node mobility. The current research efforts in DTN focus on data forwarding and reduce absence of end-to-end path between source and destination, but only limited work has been done on providing efficient data accesses to mobile users. In this paper, they propose a greatly improved energy efficiency strategy named drama aimed to improve storing and fast accessing of data in cache and also it supports cooperative caching in DTNs, which makes the sharing and coordination of cached data among multiple nodes and reduces data access delay.
