The Assessment Information Acquisition and Dissemination System Based on Delay and Disruption Tolerant MANETs for the Hiroshima National Confectionery Exposition

In the Hiroshima National Confectionery Exposition which was held from April 19 to May 12, 2013 in Hiroshima, people who participated in the Expo sampled a wide variety of confectioneries and assessed variously, for example, they are sweet and beautiful. The assessment information acquisition and dissemination system proposed by us disseminates the information using store-and-forward data transmission based on delay and disruption tolerant mobile ad hoc networks. The system can adapt to sparse and dense network environments. If a node cannot forward information to any nodes immediately, the node saves it, moves toward them, and forwards it to them. People enjoyed the Expo like a game by exchanging the information in real-time or store-and-forward. In this paper, we show the characteristics of the system, the system overview including both the software for dissemination of the assessment information using Android smartphones and the user interface (UI) of the application on the screen of Android smartphones, and finally field experimental results.
