Flexible Access and Priority Control System Based on 802.1X Authentication in Time of Disaster

Recently, mobile devices with wireless LAN function become widely used as communication tools. These devices are also recognized to be useful for communication and information gathering at stations and refuges in case of emergency such as disaster, so each institution is expected to temporarily open its access points (APs) for all users in such cases. However, for security, each institution needs to properly control their accesses according users. In addition, since a lot of people access through an AP at refuges, it is important to prioritize significant data packets. Now, we propose a flexible access and priority control system based on 802.1X authentication in time of disaster.
