Information Sharing System for Disaster Evacuation Based on Direct Communication

Abstract

This paper proposes a direct communication-based information sharing system that is supposed to be used for disaster evacuation. Although it is important to quickly grasp the situation when disaster occurred, there are several problems that block efficient sharing and aggregation of information found by evacuees, such as difficulty of operating mobile devices during evacuation, and failure of global network. In order to tackle those problems, the proposed method employs direct communication based on Bluetooth device search of smart-phones, which can be used without global network. Furthermore, the proposed method automatically selects information to be sent to other smart-phones for realizing information sharing without manual operation. This paper shows the prototype system and simulation result regarding characteristics of automatic information selection strategies.
