Efficient Data Access in Disruption Tolerant Networks Using Cooperative Caching with DRAMA
Journal Title: International Journal of Science Engineering and Advance Technology - Year 2015, Vol 3, Issue 12
Abstract
Disruption Tolerant Networks (DTNs) is characterized by low node density and unpredictable node mobility. The current research efforts in DTN focus on data forward in gand reduce absence of end-toend path between source and destination, but only limited work has been done on providing efficient data accesses to mobile users. In this paper, we 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. Our idea is to cache data at a set of nodes as network central locations (NCLs), which can be easily accessed by other nodes in the network. We propose an efficient scheme to select appropriate NCL based on probabilistic selection metric and coordinates multiple caching nodes to optimize the trade-off between data accessibility and caching overhead.
