Group Caching For Effective Data Transmission in Disruption Tolerant Networks
Journal Title: International Journal for Research in Applied Science and Engineering Technology (IJRASET) - Year 2016, Vol 4, Issue 5
Abstract
Network environment where the nodes are characterized by opportunistic connectivity are referred as Disruption /Delay Tolerant Network (DTN). In DTNs, it is difficult to maintain end-to-end connection because density of node is low, mobility of node is unpredictable and lack of global network information. It is possible to predict when the contact of nodes will occur and how long it will last, using Semi-Markov Chain process. But this process has a drawback with time complexity. So the concept of group caching is introduced, in which data is cached in group of central nodes which are frequently contacted by others. Here the data are cached at set of nodes located at the centre of the network. Without any loss of data and time delay the requested data is forwarded from source to destination. In this paper we explore some of the popular techniques for secure data transmission in DTNs.
