A Novel Data transferring from sender to receiver using the Router in Tolerant Networks

Abstract

In this paper, we propose a novel methodology to help cooperative caching in DTNs, which empowers the offering and coordination of stored information among different nodes and diminishes information access delay. A utility-based cache replacement scheme to dynamically adjust cache locations based on query history, and this scheme achieves good tradeoff between the data accessibility and access delay. A Contact Duration Aware Approach a novel caching protocol adaptive to the challenging surroundings of DTNs. To derive an adaptive caching bound for each mobile node according to its specific contact pattern with others, to limit the quantity of information it caches. In this way, both the storage space and the contact opportunities are better utilized. Extensive trace-driven simulations show that our cooperative caching protocol can significantly improve the performance of data access in DTNs
