Abstract (in Japanese) (See Japanese page) 
(in English) With the progress and widespread dissemination of Internet of Things (IoT), various application data will be generated at anywhere and anytime. In general use-case of IoT application, these data are collected in remote servers through the Internet, and users try to obtain the data via the Internet. On the other hand, some of these application data strongly depend on specific location and/or time. In this paper, we further refer to these data as spatio-temporal data. Some examples of spatio-temporal data are traffic information, weather information and advertisement like a limited-time sale. If spatio-temporal data are spread and retained within a certain area, a user within that area can receive data seamlessly and effectively. That is “local production and consumption” of spatio-temporal data are effective and feasible for location-dependent applications. Therefore, in this paper, we propose it a spatio-temporal data retention system using vehicles that retains spatio-temporal data in a certain area (target area) without any support from the infrastructure (Internet). The characteristic of a vehicle is remarkably high mobility. And all of the recent vehicles can be equipped with an onboard wireless interface. Hence, we focus on vehicular ad-hoc networks (VANETs) for constructing our spatio-temporal data retention system. However, when many vehicles simultaneously use the same communication channel, data transmissions are suffered from severe and frequent data collisions. The goal of our system is to achieve the efficient retention of spatio-temporal data in the whole target area while reducing the redundant data transmissions. In our proposed method, nodes (vehicles), which are in and around the target area, cooperatively transmit data for spreading and retaining data within the whole target area. Moreover, our proposed method employs the adaptive data transmission control based on the neighboring nodes density and the number of received data from those nodes, thereby achieving the effective data retention with the minimum number of data transmissions. From simulation results, we can confirm that our proposed method can retain the data within the whole target area while reducing the redundant data transmissions through the cooperation with not only nodes within the target area but also nodes around that area.
