Proposal of a DTN Routing Scheme for Educational Social Networks in Developing Countries

In developing countries where education is lacking, there are many regions without telecommunications infrastructure. The DTN (Delay and Disruption Tolerant Network) is a method of communication that does not rely on communications infrastructure, and one that can be used for reliable data transfer even in adverse environments. In this study, we aim to promote educational support in developing countries without telecommunications infrastructure using DTN and the educational SNS, Edmodo. We propose a system of data communication without waste, which, by considering the time in which children are free, limits distribution of content to those children who do not have free time, and distributes content as a priority to children who do have free time. Additionally, by comparing the proposed system with the conventional system in which data communication was conducted indiscriminately for all children met, we demonstrate the effectiveness of the proposed system in promoting educational support in developing countries that lack telecommunications infrastructure.
