説明

<p>In an earthquake or other disaster, we need to quickly share information on the damage and evacuation status of the affected areas. However, the information management systems used currently are centralized and may not be able to share information on the disaster area quickly due to traffic congestion and server problems. To solve this problem, a decentralized management system using blockchain has been proposed. However, blockchain has the problem that the processing time depends on the number of transactions. In this paper, we assume a prioritized management system for disaster information, and evaluate the delay time of the blockchain using queueing theory. In addition, we analyze the mean sojourn time for other information to compare the mean sojourn time for disaster information.</p>
