Abstract(in English) | Recently, a demand for flexible group communication considering the information of users' location and property is increasing drastically.To achieve this, we propose r-Space system mainly consisted of (1) (users') data collection and (2) data delivery. In this research, we focus on (1) that can apply to mobile nodes. Since r-Space system delivers application data to group users by using the information obtained at (1) in advance, the information should be maintained as much as possible.Therefore, we proposed a two-tier data collection scheme in which several nodes with similar moving pattern autonomously create group based on the condition of received periodical broadcast messages, and selects the representative nodeused for data delivery later (delivery rep. node). Furthermore, we utilize another representative nodes for data collection (collection rep. node), which are determined for individual geographical certain area (same as our previous work).Through simulation experiments, we showed that our proposed scheme can reduce number of messages transmitted on wide area wireless network by 92{%}, compared with that of case of delivery rep. nodes only, while maintaining the collected information until data delivery timing. |
