Proposal of Static Body Object Detection Methods with the DTN Routing for Life Safety Information Systems

Although the life safety information systems on the smartphones are widely spread for the sake of the emergent situations in disasters, there have been some problems to use them by people who are not good to operate or are injured. Therefore, this paper proposes the static body object detection methods with the Delay Tolerant Networking for life safety information system. In the system, the sensors on smartphones automatically detect the abnormal static situations by the time and position differences based with the Markov Chain Monte Carlo methods, and the emergent messages are automatically transmitted with the message priorities. Moreover, those messages are transmitted to the servers with the Delay Tolerant Networking. Then, the prototype system is introduced, and the experiments are discussed for the effectiveness of the proposed systems.
