A New Scheme Location Based Caching In DTN for Efficient Data Access

Archana D. Shinde, Jyoti Raghatwan

Data caching can considerably improve the efficiency of data access in a wireless network which helps to reduce the access latency and bandwidth usage. This study works in DTN network as Disruption Tolerant Network (DTN) is a network architecture that is designed to distribute communications in almost stressed, unstable environments, where that network should be focus on long lasting and frequent disruptions, high bit error rates which would tries to degrade normal communications. In this paper, the location based caching severely keeping track of a node or a set of moving nodes and answer queries related to their particular locations through their paths. Data is efficiently accessed in DTN. This work consider Network centre location (NCL) to be find out among the available nodes in the network and the cache placement problem of reducing total cost of data access in mobile networks with several data nodes with limited memory capacity. This work uses distributed algorithm that logically expands to networks with nodes and state that it appreciably performs better than another existing caching technique in all important performance metrics.
