Abstract

Most of controlling disaster managements focus on how to rescue people from disaster areas. In this paper, we propose an emergency escape system that helps people escape by themselves effectively from a disaster area in which each person owns a mobile device. We define a scenario for the proposed system in which there are five system states; they are Idle, Discovery, Subscription/Publication, Execution, and Communication states. The system uses several technologies such as service-oriented architecture, GPS and Wi-Fi positioning systems, and some sensors. The proposed system utilizes users' information such as weighted distances, weighted directions and revisit counts. The system is implemented on a double-layered MANET to reduce traffic and to collaborate with each other. We have constructed a simulator to test the proposed system. The simulation results show that the proposed system outperforms other approaches in terms of the distance and the time proving that the proposed system could be an effective life-saving rescue system.
